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 in posix_spawn_file_actions_addclose() .
FUTURE DIRECTIONS
None.
