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

NAME

12       posix_spawnattr_getsigdefault, posix_spawnattr_setsigdefault - get  and
13       set  the  spawn-sigdefault  attribute  of  a  spawn  attributes  object
14       (ADVANCED REALTIME)
15

SYNOPSIS

17       #include <signal.h>
18       #include <spawn.h>
19
20       int posix_spawnattr_getsigdefault(const posix_spawnattr_t *
21              restrict attr, sigset_t *restrict sigdefault);
22       int posix_spawnattr_setsigdefault(posix_spawnattr_t *restrict attr,
23              const sigset_t *restrict sigdefault);
24
25

DESCRIPTION

27       The posix_spawnattr_getsigdefault() function shall obtain the value  of
28       the spawn-sigdefault attribute from the attributes object referenced by
29       attr.
30
31       The posix_spawnattr_setsigdefault() function shall set the spawn-sigde‐
32       fault attribute in an initialized attributes object referenced by attr.
33
34       The  spawn-sigdefault  attribute  represents  the  set of signals to be
35       forced to  default  signal  handling  in  the  new  process  image  (if
36       POSIX_SPAWN_SETSIGDEF  is  set in the spawn-flags attribute) by a spawn
37       operation. The default value of this attribute shall be an empty signal
38       set.
39

RETURN VALUE

41       Upon   successful   completion,  posix_spawnattr_getsigdefault()  shall
42       return zero and store the value of the  spawn-sigdefault  attribute  of
43       attr into the object referenced by the sigdefault parameter; otherwise,
44       an error number shall be returned to indicate the error.
45
46       Upon  successful  completion,   posix_spawnattr_setsigdefault()   shall
47       return  zero;  otherwise, an error number shall be returned to indicate
48       the error.
49

ERRORS

51       These functions may fail if:
52
53       EINVAL The value specified by attr is invalid.
54
55
56       The posix_spawnattr_setsigdefault() function may fail if:
57
58       EINVAL The value of the attribute being set is not valid.
