PROLOG
       This  manual page is part of the POSIX Programmer's Manual.  The Linux implementation of this interface may differ (consult the correspond-
       ing 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 - 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,  unini-
       tialized.  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.
