sigset(3C) sigset(3C)

For the other functions, a

0 value indicates that the call succeeded. A -1 return value indicates an error

occurred and

errno is set to indicate the reason.

ERRORS

sigset() fails and the system signal action for sig is not changed if any of the following occur:

[EFAULT] The func argument points to memory that is not a valid part of the process

address space. Reliable detection of this error is implementation dependent.

sigset(), sighold(), sigrelse() , sigignore() , and

sigpause() fail and the system signal

action for sig is not changed if any of the following occur:

[EINVAL] sig is not a valid signal number.

[EINVAL] An attempt is made to ignore, hold, or supply a handler for a signal that cannot

be ignored, held, or caught; see signal(5).

sigpause() returns when the following occurs:

[EINTR] A signal was caught.

WARNINGS

These signal facilities should not be used in conjunction with bsdproc(3C), signal(2), sigvector(2), sig-

block(2), sigsetmask(2), sigpause(3C) and sigspace(2).
