PROLOG

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

NAME

12       posix_spawn_file_actions_destroy,    posix_spawn_file_actions_init    —
13       destroy and initialize spawn file actions object (ADVANCED REALTIME)
14

SYNOPSIS

16       #include <spawn.h>
17
18       int posix_spawn_file_actions_destroy(posix_spawn_file_actions_t
19           *file_actions);
20       int posix_spawn_file_actions_init(posix_spawn_file_actions_t
21           *file_actions);
22

DESCRIPTION

24       The   posix_spawn_file_actions_destroy()  function  shall  destroy  the
25       object referenced by  file_actions;  the  object  becomes,  in  effect,
26       uninitialized.         An        implementation        may        cause
27       posix_spawn_file_actions_destroy() to  set  the  object  referenced  by
28       file_actions to an invalid value. A destroyed spawn file actions object
29       can be reinitialized using posix_spawn_file_actions_init(); the results
30       of  otherwise  referencing  the  object after it has been destroyed are
31       undefined.
32
33       The  posix_spawn_file_actions_init()  function  shall  initialize   the
34       object  referenced  by  file_actions  to  contain  no  file actions for
35       posix_spawn() or posix_spawnp() to perform.
36
37       A    spawn    file    actions    object    is     as     defined     in
38       posix_spawn_file_actions_addclose().
39
40       The  effect  of  initializing an already initialized spawn file actions
41       object is undefined.
42

RETURN VALUE

44       Upon successful completion, these functions shall return  zero;  other‐
45       wise, an error number shall be returned to indicate the error.
46

ERRORS

48       The posix_spawn_file_actions_init() function shall fail if:
49
50       ENOMEM Insufficient  memory exists to initialize the spawn file actions
51              object.
52
53       The posix_spawn_file_actions_destroy() function may fail if:
54
55       EINVAL The value specified by file_actions is invalid.
