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

20 int posix_spawnattr_getsigmask(const posix_spawnattr_t *restrict attr,
21 sigset_t *restrict sigmask);
22 int posix_spawnattr_setsigmask(posix_spawnattr_t *restrict attr,
23 const sigset_t *restrict sigmask);
24
25
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
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
49 These functions may fail if:
50
51 EINVAL The value specified by attr is invalid.
52
53
54 The posix_spawnattr_setsigmask() function may fail if:
55
56 EINVAL The value of the attribute being set is not valid.
