.Fn Nanosleep
causes the process to sleep for the specified time. An unmasked signal will
cause it to terminate the sleep early, regardless of the
.Dv SA_RESTART
value on the interrupting signal.
.Pp
The
.Fn signanosleep
function temporarily (and atomically) sets the signal mask of the process
for the duration of the system call so that specific signals can be
nominated to cause an early termination of the sleep.
