posix_spawn_file_actions_init, posix_spawn_file_actions_destroy -- ini- tialize 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 refer- enced 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 refer- enced 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: [EINVAL] The value specified by file_actions is invalid. [ENOMEM] 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.
