NAME

6       posix_spawnattr_getsigmask,  posix_spawnattr_setsigmask  -  get and set
7       the spawn-sigmask attribute of  a  spawn  attributes  object  (ADVANCED
8       REALTIME)

SYNOPSIS

11       #include <signal.h>
12       #include <spawn.h>
13
14       int posix_spawnattr_getsigmask(const posix_spawnattr_t *restrict attr,
15              sigset_t *restrict sigmask);
16       int posix_spawnattr_setsigmask(posix_spawnattr_t *restrict attr,
17              const sigset_t *restrict sigmask);

DESCRIPTION

21       The posix_spawnattr_getsigmask() function shall obtain the value of the
22       spawn-sigmask attribute from the attributes object referenced by attr.
23
24       The posix_spawnattr_setsigmask() function shall set  the  spawn-sigmask
25       attribute in an initialized attributes object referenced by attr.
26
27       The spawn-sigmask attribute represents the signal mask in effect in the
28       new process image of a spawn operation  (if  POSIX_SPAWN_SETSIGMASK  is
29       set in the spawn-flags attribute).  The default value of this attribute
30       is unspecified.
31

RETURN VALUE

33       Upon successful completion, posix_spawnattr_getsigmask()  shall  return
34       zero  and  store  the value of the spawn-sigmask attribute of attr into
35       the object referenced by the sigmask  parameter;  otherwise,  an  error
36       number shall be returned to indicate the error.
37
38       Upon  successful  completion, posix_spawnattr_setsigmask() shall return
39       zero; otherwise, an error number shall  be  returned  to  indicate  the
40       error.
41

ERRORS

43       These functions may fail if:
44
45       EINVAL The value specified by attr is invalid.
46
47
48       The posix_spawnattr_setsigmask() function may fail if:
49
50       EINVAL The value of the attribute being set is not valid.
