# 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”).
