22 The posix_spawnattr_getsigdefault() function obtains the value of the
23 spawn-sigdefault attribute from the attributes object referenced by
24 attr.
25
26
27 The posix_spawnattr_setsigdefault() function sets the spawn-sigdefault
28 attribute in an initialized attributes object referenced by attr.

31 The spawn-sigdefault attribute represents the set of signals to be
32 forced to default signal handling in the new process image (if
33 POSIX_SPAWN_SETSIGDEF is set in the spawn-flags attribute) by a spawn
34 operation. The default value of this attribute is an empty signal set.
35
37 Upon successful completion, posix_spawnattr_getsigdefault() returns 0
38 and stores the value of the spawn-sigdefault attribute of attr into the
39 object referenced by the sigdefault parameter. Otherwise, an error
40 number is returned to indicate the error.
41
42
43 Upon successful completion, posix_spawnattr_setsigdefault() returns 0.
44 Otherwise, an error number is returned to indicate the error.

47 These functions may fail if:
48
49 EINVAL The value specified by attr is invalid.

51
52
53 The posix_spawnattr_setsigdefault() function may fail if:
54
55 EINVAL The value of the attribute being set is not valid.
