POSIX_SPAWN_FILE_ACTIONS_INIT(3) Library Functions Manual POSIX_SPAWN_FILE_ACTIONS_INIT(3)

posix_spawn_file_actions_init, posix_spawn_file_actions_destroyinitialize and destroy spawn file actions object

library “libc”

#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 () function initialize the object referenced by () to contain no file actions for () or (). Initializing an already initialized spawn file actions object may cause memory to be leaked.

The () 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.

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:

[]
Insufficient memory exists to initialize the spawn file actions object.
