POSIX_SPAWN_FILE_ACTIONS_DESTROY(3C) Standard C Library Functions

NAME


posix_spawn_file_actions_destroy, posix_spawn_file_actions_init - destroy
and initialize spawn file actions object

SYNOPSIS


#include <spawn.h>

int posix_spawn_file_actions_destroy(
posix_spawn_file_actions_t *file_actions);


int posix_spawn_file_actions_init(
posix_spawn_file_actions_t *file_actions);


DESCRIPTION


The posix_spawn_file_actions_destroy() function destroys the object
referenced by file_actions. The object becomes, in effect, uninitialized.
An implementation can cause posix_spawn_file_actions_destroy() to set the
object referenced by file_actions to an invalid value. A destroyed spawn
file actions object can be reinitialized using
posix_spawn_file_actions_init(). The results of otherwise referencing the
object after it has been destroyed are undefined.


The posix_spawn_file_actions_init() function initializes the object
referenced by file_actions to contain no file actions for posix_spawn(3C)
or posix_spawnp(3C) to perform.


A spawn file actions object is as defined in
posix_spawn_file_actions_addclose(3C).


The effect of initializing an already initialized spawn file actions
object is undefined.

RETURN VALUES


Upon successful completion, these functions return 0. 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.


The posix_spawn_file_actions_destroy() function will may if:

EINVAL
The value specified by file_actions is invalid.
