NAME

13       posix_spawn_file_actions_destroy,    posix_spawn_file_actions_init    —
14       destroy and initialize spawn file actions object (ADVANCED REALTIME)
15

SYNOPSIS

17       #include <spawn.h>
18
19       int posix_spawn_file_actions_destroy(posix_spawn_file_actions_t
20           *file_actions);
21       int posix_spawn_file_actions_init(posix_spawn_file_actions_t
22           *file_actions);
23

DESCRIPTION

25       The   posix_spawn_file_actions_destroy()  function  shall  destroy  the
26       object referenced by  file_actions;  the  object  becomes,  in  effect,
27       uninitialized.         An        implementation        may        cause
28       posix_spawn_file_actions_destroy() to  set  the  object  referenced  by
29       file_actions to an invalid value. A destroyed spawn file actions object
30       can be reinitialized using posix_spawn_file_actions_init(); the results
31       of  otherwise  referencing  the  object after it has been destroyed are
32       undefined.
33
34       The  posix_spawn_file_actions_init()  function  shall  initialize   the
35       object  referenced  by  file_actions  to  contain  no  file actions for
36       posix_spawn() or posix_spawnp() to perform.
37
38       A    spawn    file    actions    object    is     as     defined     in
39       posix_spawn_file_actions_addclose().
40
41       The  effect  of  initializing an already initialized spawn file actions
42       object is undefined.
43

RETURN VALUE

45       Upon successful completion, these functions shall return  zero;  other‐
46       wise, an error number shall be returned to indicate the error.
47

ERRORS

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