NAME
posix_spawn_file_actions_destroy,
posix_spawn_file_actions_init
--- destroy and initialize spawn file actions object
(
ADVANCED REALTIME)
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 shall destroy the object referenced by
file_actions;
the object becomes, in effect, uninitialized. An implementation may
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 shall initialize the object referenced by
file_actions
to contain no file actions for
posix_spawn()
or
posix_spawnp()
to perform.
A spawn file actions object is as defined in
posix_spawn_file_actions_addclose().
The effect of initializing an already initialized spawn file actions
object is undefined.
RETURN VALUE
Upon successful completion, these functions shall return zero;
otherwise, an error number shall be returned to indicate the error.
ERRORS
The
posix_spawn_file_actions_init()
function shall fail if:
- ENOMEM
-
Insufficient memory exists to initialize the spawn file actions object.
The
posix_spawn_file_actions_destroy()
function may fail if:
- EINVAL
-
The value specified by
file_actions
is invalid.
The following sections are informative.
EXAMPLES
None.
APPLICATION USAGE
These functions are part of the Spawn option and need not be
provided on all implementations.
RATIONALE
Refer to the RATIONALE section in
posix_spawn_file_actions_addclose().
FUTURE DIRECTIONS
None.
