PROLOG
       This manual page is part of the POSIX Programmer's Manual.  The OS
       implementation of this interface may differ (consult the corresponding
       OS manual page for details of OS behavior), or the interface may not be
       implemented on OS.

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;
       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 section in posix__spawn__file__actions__addclose().

FUTURE DIRECTIONS
       None.
