The typical use of {!Unix._exit} is after a {!Unix.fork} operation, when the child process runs into a fatal error and must exit. In this case, it is preferable to not perform any finalization action in the child process, as these actions could interfere with similar actions performed by the parent process.

The channel is initially in binary mode; use [set_binary_mode_in ic false] if text mode is desired. Text mode is supported only if the descriptor refers to a file or pipe, but is not supported if it refers to a socket. On Windows: {!Stdlib.set_binary_mode_in} always fails on channels created with this function. Beware that input channels are buffered, so more characters may have been read from the descriptor than those accessed using channel functions. Channels also keep a copy of the current position in the file. Closing the channel [ic] returned by [in_channel_of_descr fd] using [close_in ic] also closes the underlying descriptor [fd]. It is incorrect to close both the channel [ic] and the descriptor [fd]. If several channels are created on the same descriptor, one of the channels must be closed, but not the others. Consider for example a descriptor [s] connected to a socket and two channels [ic = in_channel_of_descr s] and [oc = out_channel_of_descr s]. The recommended closing protocol is to perform [close_out oc], which flushes buffered output to the socket then closes the socket. The [ic] channel must not be closed and will be collected by the GC eventually.

[map_file fd ~kind ~layout ~shared ~dims] returns a Bigarray of kind [kind], layout [layout], and dimensions as specified in [dims]. The data contained in this Bigarray are the contents of the file referred to by the file descriptor [fd] (as opened previously with {!openfile}, for example). The optional [pos] parameter is the byte offset in the file of the data being mapped; it defaults to 0 (map from the beginning of the file). If [shared] is [true], all modifications performed on the array are reflected in the file. This requires that [fd] be opened with write permissions. If [shared] is [false], modifications performed on the array are done in memory only, using copy-on-write of the modified pages; the underlying file is not affected. {!map_file} is much more efficient than reading the whole file in a Bigarray, modifying that Bigarray, and writing it afterwards. To adjust automatically the dimensions of the Bigarray to the actual size of the file, the major dimension (that is, the first dimension for an array with C layout, and the last dimension for an array with Fortran layout) can be given as [-1]. {!map_file} then determines the major dimension from the size of the file. The file must contain an integral number of sub-arrays as determined by the non-major dimensions, otherwise [Failure] is raised. If all dimensions of the Bigarray are given, the file size is matched against the size of the Bigarray. If the file is larger than the Bigarray, only the initial portion of the file is mapped to the Bigarray. If the file is smaller than the big array, the file is automatically grown to the size of the Bigarray. This requires write permissions on [fd]. Array accesses are bounds-checked, but the bounds are determined by the initial call to [map_file]. Therefore, you should make sure no other process modifies the mapped file while you're accessing it, or a SIGBUS signal may be raised. This happens, for instance, if the file is shrunk. [Invalid_argument] or [Failure] may be raised in cases where argument validation fails. @since 4.06 ._cc.l,l<@@@@@@@.@@N@-.Đ@@@@@@`..ѐ> {1 Operations on file names} .l>l>.l>la@@@@@@3........@rS1@A&unlink.ldlh.ldln@б@г.&string.ldlq.ldlw@@ @@@@@г.$unit.ldl{.ldl@@ @@@'@@@@@*@@@.ldld @-e Removes the named file.

A descriptor with the close-on-exec flag is automatically closed when the current process starts another program with one of the [exec], [create_process] and [open_process] functions. It is often a security hole to leak file descriptors opened on, say, a private file to an external program: the program, then, gets access to the private file and can do bad things with it. Hence, it is highly recommended to set all file descriptors ``close-on-exec'', except in the very few cases where a file descriptor actually needs to be transmitted to another program. The best way to set a file descriptor ``close-on-exec'' is to create it in this state. To this end, the [openfile] function has [O_CLOEXEC] and [O_KEEPEXEC] flags to enforce ``close-on-exec'' mode or ``keep-on-exec'' mode, respectively. All other operations in the Unix module that create file descriptors have an optional argument [?cloexec:bool] to indicate whether the file descriptor should be created in ``close-on-exec'' mode (by writing [~cloexec:true]) or in ``keep-on-exec'' mode (by writing [~cloexec:false]). For historical reasons, the default file descriptor creation mode is ``keep-on-exec'', if no [cloexec] optional argument is given. This is not a safe default, hence it is highly recommended to pass explicit [cloexec] arguments to operations that create file descriptors. The [cloexec] optional arguments and the [O_KEEPEXEC] flag were introduced in OCaml 4.05. Earlier, the common practice was to create file descriptors in the default, ``keep-on-exec'' mode, then call [set_close_on_exec] on those freshly-created file descriptors. This is not as safe as creating the file descriptor in ``close-on-exec'' mode because, in multithreaded programs, a window of vulnerability exists between the time when the file descriptor is created and the time [set_close_on_exec] completes. If another thread spawns another program during this window, the descriptor will leak, as it is still in the ``keep-on-exec'' mode. Regarding the atomicity guarantees given by [~cloexec:true] or by the use of the [O_CLOEXEC] flag: on all platforms it is guaranteed that a concurrently-executing Caml thread cannot leak the descriptor by starting a new process. On Linux, this guarantee extends to concurrently-executing C threads. As of Feb 2017, other operating systems lack the necessary system calls and still expose a window of vulnerability during which a C thread can see the newly-created file descriptor in ``keep-on-exec'' mode. 5N||5O/@@@@@@@5g@@@35b@@@@@@13clear_close_on_exec5e15f1@б@г*file_descr5p15q1@@ @@@435r5r5r5r5r5r5r5r@J_8@A@@г5-$unit5151@@ @@@5@@@@@6@@@51 @3򐠠 W Clear the ``close-on-exec'' flag on the given descriptor.

On Windows, [~to_dir] indicates if the symbolic link points to a directory or a file; if omitted, [symlink] examines [src] using [stat] and picks appropriately, if [src] does not exist then [false] is assumed (for this reason, it is recommended that the [~to_dir] parameter be specified in new code). On Unix, [~to_dir] is ignored. Windows symbolic links are available in Windows Vista onwards. There are some important differences between Windows symlinks and their POSIX counterparts. Windows symbolic links come in two flavours: directory and regular, which designate whether the symbolic link points to a directory or a file. The type must be correct - a directory symlink which actually points to a file cannot be selected with chdir and a file symlink which actually points to a directory cannot be read or written (note that Cygwin's emulation layer ignores this distinction). When symbolic links are created to existing targets, this distinction doesn't matter and [symlink] will automatically create the correct kind of symbolic link. The distinction matters when a symbolic link is created to a non-existent target. The other caveat is that by default symbolic links are a privileged operation. Administrators will always need to be running elevated (or with UAC disabled) and by default normal user accounts need to be granted the SeCreateSymbolicLinkPrivilege via Local Security Policy (secpol.msc) or via Active Directory. {!has_symlink} can be used to check that a process is able to create symbolic links.

The fourth argument is the maximal timeout, in seconds; a negative fourth argument means no timeout (unbounded wait). The result is composed of three sets of descriptors: those ready for reading (first component), ready for writing (second component), and over which an exceptional condition is pending (third component). On Windows, if one of descriptor lists exceeds [FD_SETSIZE] elements (64 by default), or if at least one non-socket file descriptor is used, the maximal timeout is capped to 2{^32} milliseconds.

The region starts at the current read/write position for [fd] (as set by {!lseek}), and extends [len] bytes forward if [len] is positive, [len] bytes backwards if [len] is negative, or to the end of the file if [len] is zero. A write lock prevents any other process from acquiring a read or write lock on the region. A read lock prevents any other process from acquiring a write lock on the region, but lets other processes acquire read locks on it. The [F_LOCK] and [F_TLOCK] commands attempts to put a write lock on the specified region. The [F_RLOCK] and [F_TRLOCK] commands attempts to put a read lock on the specified region. If one or several locks put by another process prevent the current process from acquiring the lock, [F_LOCK] and [F_RLOCK] block until these locks are removed, while [F_TLOCK] and [F_TRLOCK] fail immediately with an exception. The [F_ULOCK] removes whatever locks the current process has on the specified region. Finally, the [F_TEST] command tests whether a write lock can be acquired on the specified region, without actually putting a lock. It returns immediately if successful, or fails otherwise. What happens when a process tries to lock a region of a file that is already locked by the same process depends on the OS. On POSIX-compliant systems, the second lock operation succeeds and may "promote" the older lock from read lock to write lock. On Windows, the second lock operation will block or fail.

Errors defined in the POSIX standard and additional errors from UNIX98 and BSD. All other errors are mapped to EUNKNOWNERR. c s* Raised by the system calls below when an error is encountered. The first component is the error code; the second component is the function name; the third component is the string parameter to the function, if it has one, or the empty string otherwise. {!UnixLabels.Unix_error} and {!Unix.Unix_error} are the same, and catching one will catch the other. {q 3* Return a string describing the given error code. { * [handle_unix_error f x] applies [f] to [x] and returns the result. If the exception {!Unix_error} is raised, it prints a message describing the error and exits with code 2. z (* {1 Access to the process environment} z * Return the process environment, as an array of strings with the format ``variable=value''. The returned array is empty if the process has special privileges. zN (* Return the process environment, as an array of strings with the format ``variable=value''. Unlike {!environment}, this function returns a populated array even if the process has special privileges. See the documentation for {!unsafe_getenv} for more details. @since 4.12 y * Return the value associated to a variable in the process environment, unless the process has special privileges. @raise Not_found if the variable is unbound or the process has special privileges. This function is identical to {!Sys.getenv}. y * Return the value associated to a variable in the process environment. Unlike {!getenv}, this function returns the value even if the process has special privileges. It is considered unsafe because the programmer of a setuid or setgid program must be careful to avoid using maliciously crafted environment variables in the search path for executables, the locations for temporary files or logs, and the like. @raise Not_found if the variable is unbound. @since 4.06 ym * [putenv name value] sets the value associated to a variable in the process environment. [name] is the name of the environment variable, and [value] its new associated value. y7* {1 Process handling} x Y* The process terminated normally by [exit]; the argument is the return code. xӠ T* The process was killed by a signal; the argument is the signal number. x U* The process was stopped by a signal; the argument is the signal number. x F* The termination status of a process. See {!Sys.signal} for the definitions of the standard signal numbers. On Windows: only [WEXITED] is used (as there are no inter-process signals) but with specific return codes to indicate special termination causes. Look for [NTSTATUS] values in the Windows documentation to decode such error return codes. In particular, [STATUS_ACCESS_VIOLATION] error code is the 32-bit [0xC0000005]: as [Int32.of_int 0xC0000005] is [-1073741819], [WEXITED -1073741819] is the Windows equivalent of [WSIGNALED Sys.sigsegv]. x f* Do not block if no child has died yet, but immediately return with a pid equal to 0. wࠠ 6* Report also the children that receive stop signals. w̠8* Flags for {!waitpid}. w * [execv prog args] execute the program in file [prog], with the arguments [args], and the current process environment. Note that the first argument, [args.(0)], is by convention the filename of the program being executed, just like [Sys.argv.(0)]. These [execv*] functions never return: on success, the current program is replaced by the new one. On Windows: the CRT simply spawns a new process and exits the current one. This will have unwanted consequences if e.g. another process is waiting on the current one. Using {!create_process} or one of the [open_process_*] functions instead is recommended. @raise Unix_error on failure w h* Same as {!execv}, except that the third argument provides the environment to the program executed. v} H* Same as {!execv}, except that the program is searched in the path. v I* Same as {!execve}, except that the program is searched in the path. u * Fork a new process. The returned integer is 0 for the child process, the pid of the child process for the parent process. It fails if the OCaml process is multi-core (any domain has been spawned). In addition, if any thread from the Thread module has been spawned, then the child process might be in a corrupted state. @raise Invalid_argument on Windows. Use {!create_process} or threads instead. @raise Failure if any domain has been spawned. u= * Wait until one of the children processes die, and return its pid and termination status. @raise Invalid_argument on Windows. Use {!waitpid} instead. tݠ * Same as {!wait}, but waits for the child process whose pid is given. A pid of [-1] means wait for any child. A pid of [0] means wait for any child in the same process group as the current process. Negative pid arguments represent process groups. The list of options indicates whether [waitpid] should return immediately without waiting, and whether it should report stopped children. On Windows: can only wait for a given PID, not any child process. tY * Execute the given command, wait until it terminates, and return its termination status. The string is interpreted by the shell [/bin/sh] (or the command interpreter [cmd.exe] on Windows) and therefore can contain redirections, quotes, variables, etc. To properly quote whitespace and shell special characters occurring in file names or command arguments, the use of {!Filename.quote_command} is recommended. The result [WEXITED 127] indicates that the shell couldn't be executed. t * Terminate the calling process immediately, returning the given status code to the operating system: usually 0 to indicate no errors, and a small positive integer to indicate failure. Unlike {!Stdlib.exit}, {!Unix._exit} performs no finalization whatsoever: functions registered with {!Stdlib.at_exit} are not called, input/output channels are not flushed, and the C run-time system is not finalized either. The typical use of {!Unix._exit} is after a {!Unix.fork} operation, when the child process runs into a fatal error and must exit. In this case, it is preferable to not perform any finalization action in the child process, as these actions could interfere with similar actions performed by the parent process. For example, output channels should not be flushed by the child process, as the parent process may flush them again later, resulting in duplicate output. @since 4.12 sϠ !* Return the pid of the process. s p* Return the pid of the parent process. @raise Invalid_argument on Windows (because it is meaningless) sC * Change the process priority. The integer argument is added to the ``nice'' value. (Higher values of the ``nice'' value mean lower priorities.) Return the new nice value. @raise Invalid_argument on Windows r>* {1 Basic file input/output} r⠠ )* The abstract type of file descriptors. r %* File descriptor for standard input.ro &* File descriptor for standard output.r; &* File descriptor for standard error. r3* Open for reading qڠ3* Open for writing qƠ?* Open for reading and writing q<* Open in non-blocking mode q2* Open for append q8* Create if nonexistent qv #* Truncate to 0 length if existing qb3* Fail if existing qN (* Don't make this dev a controlling tty q: f* Writes complete as `Synchronised I/O data integrity completion' q& f* Writes complete as `Synchronised I/O file integrity completion' q ]* Reads complete as writes (depending on O_SYNC/O_DSYNC) p b* Windows only: allow the file to be deleted while still open pꠠ * Set the close-on-exec flag on the descriptor returned by {!openfile}.

Text mode is supported only if the descriptor refers to a file or pipe, but is not supported if it refers to a socket. On Windows: {!Stdlib.set_binary_mode_in} always fails on channels created with this function. Beware that input channels are buffered, so more characters may have been read from the descriptor than those accessed using channel functions. Channels also keep a copy of the current position in the file. Closing the channel [ic] returned by [in_channel_of_descr fd] using [close_in ic] also closes the underlying descriptor [fd]. It is incorrect to close both the channel [ic] and the descriptor [fd]. If several channels are created on the same descriptor, one of the channels must be closed, but not the others. Consider for example a descriptor [s] connected to a socket and two channels [ic = in_channel_of_descr s] and [oc = out_channel_of_descr s]. The recommended closing protocol is to perform [close_out oc], which flushes buffered output to the socket then closes the socket. The [ic] channel must not be closed and will be collected by the GC eventually. h栠 * Create an output channel writing on the given descriptor. The channel is initially in binary mode; use [set_binary_mode_out oc false] if text mode is desired. Text mode is supported only if the descriptor refers to a file or pipe, but is not supported if it refers to a socket. On Windows: {!Stdlib.set_binary_mode_out} always fails on channels created with this function. Beware that output channels are buffered, so you may have to call {!Stdlib.flush} to ensure that all data has been sent to the descriptor. Channels also keep a copy of the current position in the file. Closing the channel [oc] returned by [out_channel_of_descr fd] using [close_out oc] also closes the underlying descriptor [fd].

These alternate functions represent positions and sizes by 64-bit integers (type [int64]) instead of regular integers (type [int]), thus allowing operating on files whose sizes are greater than [max_int]. \[ * {1 Mapping files into memory} \J? thwart tools/sync_stdlib_docs [bb[bb@ * Memory mapping of a file as a Bigarray. [map_file fd ~kind ~layout ~shared ~dims] returns a Bigarray of kind [kind], layout [layout], and dimensions as specified in [dims]. The data contained in this Bigarray are the contents of the file referred to by the file descriptor [fd] (as opened previously with {!openfile}, for example). The optional [pos] parameter is the byte offset in the file of the data being mapped; it defaults to 0 (map from the beginning of the file). If [shared] is [true], all modifications performed on the array are reflected in the file. This requires that [fd] be opened with write permissions. If [shared] is [false], modifications performed on the array are done in memory only, using copy-on-write of the modified pages; the underlying file is not affected. {!map_file} is much more efficient than reading the whole file in a Bigarray, modifying that Bigarray, and writing it afterwards. To adjust automatically the dimensions of the Bigarray to the actual size of the file, the major dimension (that is, the first dimension for an array with C layout, and the last dimension for an array with Fortran layout) can be given as [-1]. {!map_file} then determines the major dimension from the size of the file. The file must contain an integral number of sub-arrays as determined by the non-major dimensions, otherwise [Failure] is raised. If all dimensions of the Bigarray are given, the file size is matched against the size of the Bigarray. If the file is larger than the Bigarray, only the initial portion of the file is mapped to the Bigarray. If the file is smaller than the big array, the file is automatically grown to the size of the Bigarray. This requires write permissions on [fd]. Array accesses are bounds-checked, but the bounds are determined by the initial call to [map_file]. Therefore, you should make sure no other process modifies the mapped file while you're accessing it, or a SIGBUS signal may be raised. This happens, for instance, if the file is shrunk. [Invalid_argument] or [Failure] may be raised in cases where argument validation fails. @since 4.06 [?* {1 Operations on file names} Z堠 * Removes the named file.

See {!set_close_on_exec} for documentation on the [cloexec] optional argument. U d* Set the ``non-blocking'' flag on the given descriptor. When the non-blocking flag is set, reading on a descriptor on which there is temporarily no data available raises the [EAGAIN] or [EWOULDBLOCK] error instead of blocking; writing on a descriptor on which there is temporarily no room for writing also raises [EAGAIN] or [EWOULDBLOCK]. UE R* Clear the ``non-blocking'' flag on the given descriptor. See {!set_nonblock}.T |* Set the ``close-on-exec'' flag on the given descriptor. A descriptor with the close-on-exec flag is automatically closed when the current process starts another program with one of the [exec], [create_process] and [open_process] functions. It is often a security hole to leak file descriptors opened on, say, a private file to an external program: the program, then, gets access to the private file and can do bad things with it. Hence, it is highly recommended to set all file descriptors ``close-on-exec'', except in the very few cases where a file descriptor actually needs to be transmitted to another program. The best way to set a file descriptor ``close-on-exec'' is to create it in this state. To this end, the [openfile] function has [O_CLOEXEC] and [O_KEEPEXEC] flags to enforce ``close-on-exec'' mode or ``keep-on-exec'' mode, respectively. All other operations in the Unix module that create file descriptors have an optional argument [?cloexec:bool] to indicate whether the file descriptor should be created in ``close-on-exec'' mode (by writing [~cloexec:true]) or in ``keep-on-exec'' mode (by writing [~cloexec:false]). For historical reasons, the default file descriptor creation mode is ``keep-on-exec'', if no [cloexec] optional argument is given. This is not a safe default, hence it is highly recommended to pass explicit [cloexec] arguments to operations that create file descriptors. The [cloexec] optional arguments and the [O_KEEPEXEC] flag were introduced in OCaml 4.05. Earlier, the common practice was to create file descriptors in the default, ``keep-on-exec'' mode, then call [set_close_on_exec] on those freshly-created file descriptors. This is not as safe as creating the file descriptor in ``close-on-exec'' mode because, in multithreaded programs, a window of vulnerability exists between the time when the file descriptor is created and the time [set_close_on_exec] completes. If another thread spawns another program during this window, the descriptor will leak, as it is still in the ``keep-on-exec'' mode. Regarding the atomicity guarantees given by [~cloexec:true] or by the use of the [O_CLOEXEC] flag: on all platforms it is guaranteed that a concurrently-executing Caml thread cannot leak the descriptor by starting a new process. On Linux, this guarantee extends to concurrently-executing C threads. As of Feb 2017, other operating systems lack the necessary system calls and still expose a window of vulnerability during which a C thread can see the newly-created file descriptor in ``keep-on-exec'' mode.

The pid of the new process is returned immediately; the new process executes concurrently with the current process. The standard input and outputs of the new process are connected to the descriptors [stdin], [stdout] and [stderr].

The executable file [prog] is searched in the path. The new process has the same environment as the current process.

The {!Filename.quote_command} function can be used to quote the command and its arguments as appropriate for the shell being used.

N * Same as {!open_process_out}, but redirects both the standard input and standard output of the command to pipes connected to the two returned channels.

H젠5* {1 Symbolic links} HѠ? thwart tools/sync_stdlib_docs yUlzU@ * [symlink ?to_dir ~src ~dst] creates the file [dst] as a symbolic link to the file [src]. On Windows, [~to_dir] indicates if the symbolic link points to a directory or a file; if omitted, [symlink] examines [src] using [stat] and picks appropriately, if [src] does not exist then [false] is assumed (for this reason, it is recommended that the [~to_dir] parameter be specified in new code). On Unix, [~to_dir] is ignored. Windows symbolic links are available in Windows Vista onwards. There are some important differences between Windows symlinks and their POSIX counterparts. Windows symbolic links come in two flavours: directory and regular, which designate whether the symbolic link points to a directory or a file. The type must be correct - a directory symlink which actually points to a file cannot be selected with chdir and a file symlink which actually points to a directory cannot be read or written (note that Cygwin's emulation layer ignores this distinction). When symbolic links are created to existing targets, this distinction doesn't matter and [symlink] will automatically create the correct kind of symbolic link. The distinction matters when a symbolic link is created to a non-existent target. The other caveat is that by default symbolic links are a privileged operation. Administrators will always need to be running elevated (or with UAC disabled) and by default normal user accounts need to be granted the SeCreateSymbolicLinkPrivilege via Local Security Policy (secpol.msc) or via Active Directory. {!has_symlink} can be used to check that a process is able to create symbolic links. Hm 3* Returns [true] if the user is able to create symbolic links. On Windows, this indicates that the user not only has the SeCreateSymbolicLinkPrivilege but is also running elevated, if necessary. On other platforms, this is simply indicates that the symlink system call is available. @since 4.03 H' (* Read the contents of a symbolic link. Gᠠ.* {1 Polling} GƠ -* Wait until some input/output operations become possible on some channels. The three list arguments are, respectively, a set of descriptors to check for reading (first argument), for writing (second argument), or for exceptional conditions (third argument). The fourth argument is the maximal timeout, in seconds; a negative fourth argument means no timeout (unbounded wait). The result is composed of three sets of descriptors: those ready for reading (first component), ready for writing (second component), and over which an exceptional condition is pending (third component). On Windows, if one of descriptor lists exceeds [FD_SETSIZE] elements (64 by default), or if at least one non-socket file descriptor is used, the maximal timeout is capped to 2{^32} milliseconds.

F A* [lockf fd ~mode ~len] puts a lock on a region of the file opened as [fd]. The region starts at the current read/write position for [fd] (as set by {!lseek}), and extends [len] bytes forward if [len] is positive, [len] bytes backwards if [len] is negative, or to the end of the file if [len] is zero. A write lock prevents any other process from acquiring a read or write lock on the region. A read lock prevents any other process from acquiring a write lock on the region, but lets other processes acquire read locks on it. The [F_LOCK] and [F_TLOCK] commands attempts to put a write lock on the specified region. The [F_RLOCK] and [F_TRLOCK] commands attempts to put a read lock on the specified region. If one or several locks put by another process prevent the current process from acquiring the lock, [F_LOCK] and [F_RLOCK] block until these locks are removed, while [F_TLOCK] and [F_TRLOCK] fail immediately with an exception. The [F_ULOCK] removes whatever locks the current process has on the specified region. Finally, the [F_TEST] command tests whether a write lock can be acquired on the specified region, without actually putting a lock. It returns immediately if successful, or fails otherwise. What happens when a process tries to lock a region of a file that is already locked by the same process depends on the OS. On POSIX-compliant systems, the second lock operation succeeds and may "promote" the older lock from read lock to write lock. On Windows, the second lock operation will block or fail.

The second argument is the duration of the break, in 0.1s units; 0 means standard duration (0.25s). @raise Invalid_argument on Windows  H ~* Waits until all output written on the given file descriptor has been transmitted. @raise Invalid_argument on Windows   G* Discard data written on the given file descriptor but not yet transmitted, or data received but not yet read, depending on the second argument: [TCIFLUSH] flushes data received but not read, [TCOFLUSH] flushes data written but not transmitted, and [TCIOFLUSH] flushes both. @raise Invalid_argument on Windows  D M* Suspend or restart reception or transmission of data on the given file descriptor, depending on the second argument: [TCOOFF] suspends output, [TCOON] restarts output, [TCIOFF] transmits a STOP character to suspend input, and [TCION] transmits a START character to restart input. @raise Invalid_argument on Windows w * Put the calling process in a new session and detach it from its controlling terminal. @raise Invalid_argument on Windows 1@K0../../ocamlc.opt)-nostdlib"-I,../../stdlib"-c(-absname"-w5+a-4-9-41-42-44-45-48+-warn-error"+A*-bin-annot"-g0-strict-sequence/-strict-formats)-nolabels#-pp .gawk -f ../../stdlib/expand_module_aliases.awk.unixLabels.mli U/home/ci/builds/workspace/main/flambda/false/label/ocaml-ubuntu-latest/otherlibs/unix @@0+!'O@. 3@@@8CamlinternalFormatBasics0oZ2t,ݠ&Stdlib0y{x!O!0Stdlib__Bigarray0M&۩9|HOT/Stdlib__Complex0\lEWN2+Stdlib__Sys0M xIor 0 8RmZuDq砠Ð0it_ktYp5@0it_ktYp5AZ[F`a@ F }vug}}@p@@+,~-}@ @4ǐ4UU@}~\@@D@> 6k6@##@h@QɐR@  h.fȰvRu'@WHW@B2f21ig@ְ^^phg&@@'&ΰSTK\j\@vȓuϓ;@..ٓ@362?p?CܕBܰvu@ؒ4'&@$%7&f%@@4P4f>fx|}@֐ &%>=cMacb5ll@YZ@igzސ{@&$%o:o@@'&@..e@@ " LMk8k@J:9:;ؐ<@(s'`@WaW@33??@7@Zh7u7jݓjT@ڕ&a%۰n@HQHZ]Z^*^d@AA@IɒJtfAf{@@hߓc@/.@/u/İCDEqD@F CBְ^@@WG  *+%D Chj@QUQʰXY%@J9Idb@kjjkkwvN@ՐQ=c=i4g@44m>f>@ F #L@qDr@@cb@%(“'+`+c@L @=Rm@@;f;@@@@@2*%Ǔ%fXf@@ X@NO @$#$//[DD~#}@88ǰ@@ : #@XX@@ٰmn -@A-Ag@FE@ wtn@LڐMC_`iĕhm@'&7֐8ibg@ ِ (t0^t^@ X   L@4h4ih,@@@MNI@ljl@rr@X@:ޕ:i@@  8`0@R ==ɰlڐm;@'&@q>q@̕ʰ99V?@kГkA˓@@01B@ ʓ SSzpz7@88@PQ.@8۰BǐC@!!NVW+$V@@;:^^Jegd:@APA@ܓDt(t@n@u)@ST3X4Xn@=xx@^_C@==Ұ-@;:@v E2D/@(ے)EjDmxwJw@rx"v@RېSdؓ.{@ȰZ<Zv~h@p@:SwÓv@X;X\@@@L@ oՐp@414WݐX\\x@IaIuu:@""YY@@@&&^6x6@3A3ED°kisty@bb@f:Z9g*g4ΐg@zְ##d@KMJ߰LMzvz@|͐}Pt@@}@wٰ5S4;S;@<= @FʒGTn_nŰ_@`~/</v22|@4V4?S@w’y<@@  uhihI@eÕd@wv@>,HH@$T°df@ޓ@IѓIec@ē@e ced|@L K}!@jЕiv~~l@$G$CCMKKHOrO@!* հ+s,%8}8i@ҕWWpvv@{%{_@-.Q]]W$@@zz,@JKxwx2J@$ې%9@@33@yRS@#$j[[@\@LKx@w9@> @ED__k{|@dɰEDQQWzz@@@  88N@@56 @6j6аHIo n߰e @*ē)۰??G͕GdlʓlSppR@77UjV.@  X++ưDZDGÕGLccư@12J=>!^9^@!"[AeA@@//1b1!@ߓpa7a@v@߰*){{I@fgKpp˰xw@()Egbg9A@@@;v;2JJxoWo@NiN~W~@PcP@ l0k0@@@>8E8m8ǐ9@7[7<ݐ?m]l@a@@W{W@##ܰ<<}ww@ (@@<< hhx@zz@@  inlVk @y\\U@ڰfeV@@Rb|o{@!)!t'“'@S3S@bcyx@@0j0>molmmeyVxC@@  *KJ@t@g+e@'œ'+Q*{vw+@|@&T&+*R``@v@zX@@HIN@2`<@@BAȰRjR@&ذMMLǰXҐY  ^@00s44IwINԐOss@@ 5@#@&`@@;
