POSIX_SP..._DESTROY(3P) POSIX Programmer's ManualPOSIX_SP..._DESTROY(3P)
This manual page is part of the POSIX Programmer's Manual. The
Linux implementation of this interface may differ (consult the
corresponding Linux manual page for details of Linux behavior),
or the interface may not be implemented on Linux.
posix_spawn_file_actions_destroy, posix_spawn_file_actions_init —
destroy and initialize spawn file actions object (ADVANCED
REALTIME)
#include <spawn.h>
int posix_spawn_file_actions_destroy(posix_spawn_file_actions_t
*file_actions);
int posix_spawn_file_actions_init(posix_spawn_file_actions_t
*file_actions);
The posix_spawn_file_actions_destroy() function shall destroy the
object referenced by file_actions; the object becomes, in effect,
uninitialized. An implementation may cause
posix_spawn_file_actions_destroy() to set the object referenced
by file_actions to an invalid value. A destroyed spawn file
actions object can be reinitialized using
posix_spawn_file_actions_init(); the results of otherwise
referencing the object after it has been destroyed are undefined.
The posix_spawn_file_actions_init() function shall initialize the
object referenced by file_actions to contain no file actions for
posix_spawn() or posix_spawnp() to perform.
A spawn file actions object is as defined in
posix_spawn_file_actions_addclose(3p).
The effect of initializing an already initialized spawn file
actions object is undefined.
Upon successful completion, these functions shall return zero;
otherwise, an error number shall be returned to indicate the
error.
The posix_spawn_file_actions_init() function shall fail if:
ENOMEM Insufficient memory exists to initialize the spawn file
actions object.
The posix_spawn_file_actions_destroy() function may fail if:
EINVAL The value specified by file_actions is invalid.
The following sections are informative.
None.
These functions are part of the Spawn option and need not be
provided on all implementations.
Refer to the RATIONALE section in
posix_spawn_file_actions_addclose(3p).
None.
