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

13       posix_spawnattr_getsigmask, posix_spawnattr_setsigmask —  get  and  set
14       the  spawn-sigmask  attribute  of  a  spawn attributes object (ADVANCED
15       REALTIME)
16

SYNOPSIS

18       #include <signal.h>
19       #include <spawn.h>
20
21       int posix_spawnattr_getsigmask(const posix_spawnattr_t *restrict attr,
22           sigset_t *restrict sigmask);
23       int posix_spawnattr_setsigmask(posix_spawnattr_t *restrict attr,
24           const sigset_t *restrict sigmask);
25

DESCRIPTION

27       The posix_spawnattr_getsigmask() function shall obtain the value of the
28       spawn-sigmask attribute from the attributes object referenced by attr.
29
30       The  posix_spawnattr_setsigmask()  function shall set the spawn-sigmask
31       attribute in an initialized attributes object referenced by attr.
32
33       The spawn-sigmask attribute represents the signal mask in effect in the
34       new  process  image  of a spawn operation (if POSIX_SPAWN_SETSIGMASK is
35       set in the spawn-flags attribute). The default value of this  attribute
36       is unspecified.
37

RETURN VALUE

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

ERRORS

49       These functions may fail if:
50
51       EINVAL The value specified by attr is invalid.
52
53       The posix_spawnattr_setsigmask() function may fail if:
54
55       EINVAL The value of the attribute being set is not valid.
