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.
