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.
