POSIX_SPAWN_FILE_ACTIONS_DESTROY(3P)                POSIX Programmer's Manual               POSIX_SPAWN_FILE_ACTIONS_DESTROY(3P)



PROLOG
       This  manual  page is part of the POSIX Programmer's Manual.  The Linux implementation of this interface may differ (con-
       sult 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 unde-
       fined.

       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.
