POSIX_SPAWN_FILE_ACTIONS_INIT(3) |
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:
-
[EINVAL]
-
The value specified by file_actions is invalid.
-
[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 and imported for NetBSD 6.0.
