POSIX_SPAWN_FILE_ACTIONS_INIT(3) FreeBSD Library Functions Manual
NAME posix_spawn_file_actions_init, posix_spawn_file_actions_destroy - initialize and destroy spawn file actions object
LIBRARY Standard C Library (libc, -lc)
SYNOPSIS #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);
DESCRIPTION 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.
RETURN VALUES Upon successful completion, these functions return zero; otherwise, an error number is returned to indicate the error.
ERRORS The posix_spawn_file_actions_init() function will fail if:
[ENOMEM] Insufficient memory exists to initialize the spawn file actions object.

STANDARDS The posix_spawn_file_actions_init() and posix_spawn_file_actions_destroy() functions conform to IEEE Std 1003.1-2001 ("POSIX.1").
HISTORY The posix_spawn_file_actions_init() and posix_spawn_file_actions_destroy() functions first appeared in FreeBSD 8.0.
