NAME

6       posix_spawn_file_actions_destroy,    posix_spawn_file_actions_init    -
7       destroy and initialize spawn file actions object (ADVANCED REALTIME)

SYNOPSIS

10       #include <spawn.h>
11
12       int posix_spawn_file_actions_destroy(posix_spawn_file_actions_t *
13              file_actions);
14       int posix_spawn_file_actions_init(posix_spawn_file_actions_t *
15              file_actions);

DESCRIPTION

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

RETURN VALUE

39       Upon  successful  completion, these functions shall return zero; other‐
40       wise, an error number shall be returned to indicate the error.
41

ERRORS

43       The posix_spawn_file_actions_init() function shall fail if:
44
45       ENOMEM Insufficient memory exists to initialize the spawn file  actions
46              object.
47
48
49       The posix_spawn_file_actions_destroy() function may fail if:
50
51       EINVAL The value specified by file_actions is invalid.
