The
sigwait()
function suspends execution of the calling thread until the
delivery of one of the signals specified in the signal set
set.
The function accepts the signal
(removes it from the pending list of signals),
and returns the signal number in
sig.
The operation of
sigwait()
is the same as
sigwaitinfo(),
except that:
*
sigwait()
only returns the signal number, rather than a
siginfo_t
structure describing the signal.
*
The return values of the two functions are different.
RETURN VALUE
On success,
sigwait()
returns 0.
On error, it returns a positive error number.
