posix_spawn_file_actions_destroy - Man Page

destroy and initialize spawn file actions object (ADVANCED REALTIME)


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.


#include <spawn.h>

int posix_spawn_file_actions_destroy(posix_spawn_file_actions_t
int posix_spawn_file_actions_init(posix_spawn_file_actions_t


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.


The posix_spawn_file_actions_init() function shall fail if:


Insufficient memory exists to initialize the spawn file actions object.

The posix_spawn_file_actions_destroy() function may fail if:


The value specified by file_actions is invalid.

The following sections are informative.



Application Usage

These functions are part of the Spawn option and need not be provided on all implementations.


Refer to the RATIONALE section in posix_spawn_file_actions_addclose().
