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(3p).

       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(3p).

FUTURE DIRECTIONS

       None.
