POSIX_SPAWN_FILE_ACTIONS_INIT(3) Library Functions Manual POSIX_SPAWN_FILE_ACTIONS_INIT(3)

posix_spawn_file_actions_init, posix_spawn_file_actions_destroy
initialize and destroy spawn file actions object

Standard C Library (libc, -lc)

#include <spawn.h>

int
posix_spawn_file_actions_init(posix_spawn_file_actions_t * file_actions);

int
posix_spawn_file_actions_destroy(posix_spawn_file_actions_t * file_actions);

The posix_spawn_file_actions_init() function initialize the object referenced by file_actions() to contain no file actions for posix_spawn() or posix_spawnp(). Initializing an already initialized spawn file actions object may cause memory to be leaked.

The posix_spawn_file_actions_destroy() function destroy the object referenced by file_actions; the object becomes, in effect, uninitialized. A destroyed spawn file actions object can be reinitialized using posix_spawn_file_actions_init(). The object should not be used after it has been destroyed.

Upon successful completion, these functions return zero; otherwise, an error number is returned to indicate the error.

The posix_spawn_file_actions_init() function will fail if:
[]
The value specified by file_actions is invalid.
[]
Insufficient memory exists to initialize the spawn file actions object.

The posix_spawn_file_actions_init() and posix_spawn_file_actions_destroy() functions conform to IEEE Std 1003.1-2001 (“POSIX.1”).

The posix_spawn_file_actions_init() and posix_spawn_file_actions_destroy() functions first appeared in FreeBSD 8.0 and imported for NetBSD 6.0.
