or the interface may not be implemented on Linux.
Имя (Name)
posix_spawn_file_actions_destroy, posix_spawn_file_actions_init —
destroy and initialize spawn file actions object (ADVANCED
REALTIME)
Синопсис (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);
Описание (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(3p).
The effect of initializing an already initialized spawn file
actions object is undefined.
Возвращаемое значение (Return value)
Upon successful completion, these functions shall return zero;
otherwise, an error number shall be returned to indicate the
error.
Ошибки (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.
