initialize spawn file actions object (
ADVANCED REALTIME)
Návod, kniha: POSIX Programmer's Manual
#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 );
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.
Upon successful completion, these functions shall return zero; otherwise, an
error number shall be returned to indicate the error.
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.
None.
These functions are part of the Spawn option and need not be provided on all
implementations.
Refer to the RATIONALE in
posix_spawn_file_actions_addclose() .
