PROLOG
       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.
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;  other-
       wise, 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.

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
