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
26 The posix_spawnattr_getsigmask() function shall obtain the value of the
27 spawn-sigmask attribute from the attributes object referenced by attr.
28
29 The posix_spawnattr_setsigmask() function shall set the spawn-sigmask
30 attribute in an initialized attributes object referenced by attr.
31
32 The spawn-sigmask attribute represents the signal mask in effect in the
33 new process image of a spawn operation (if POSIX_SPAWN_SETSIGMASK is
34 set in the spawn-flags attribute). The default value of this attribute
35 is unspecified.
36
38 Upon successful completion, posix_spawnattr_getsigmask() shall return
39 zero and store the value of the spawn-sigmask attribute of attr into
40 the object referenced by the sigmask parameter; otherwise, an error
41 number shall be returned to indicate the error.
42
43 Upon successful completion, posix_spawnattr_setsigmask() shall return
44 zero; otherwise, an error number shall be returned to indicate the
45 error.
46
48 These functions may fail if:
49
50 EINVAL The value specified by attr is invalid.
51
52 The posix_spawnattr_setsigmask() function may fail if:
53
54 EINVAL The value of the attribute being set is not valid.

62 These functions are part of the Spawn option and need not be provided
