This manual page is part of the POSIX Programmer's Manual. The Linux
implementation of this interface may differ (consult the corresponding
Linux manual page for details of Linux behavior), or the interface may
not be implemented on Linux.
NAME
posix_spawn_file_actions_destroy, posix_spawn_file_actions_init -- de-
stroy 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 ob-
ject referenced by file_actions; the object becomes, in effect, unini-
tialized. An implementation may cause posix_spawn_file_actions_de-
stroy() 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 ob-
ject 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_ac-
tions_addclose().
The effect of initializing an already initialized spawn file actions
object is undefined.
RETURN VALUE
Upon successful completion, these functions shall return zero; other-
wise, 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.
