sigpause(3) C LIBRARY FUNCTIONS sigpause(3)
NAME
sigpause - automically release blocked signals and wait for
interrupt
SYNOPSIS
cc [ flag... ] file ... -lucb sigpause(sigmask)
int sigmask;
DESCRIPTION
sigpause assigns sigmask to the set of masked signals and
then waits for a signal to arrive; on return the set of
masked signals is restored. sigmask is usually 0 to indi-
cate that no signals are now to be blocked. sigpause always
terminates by being interrupted, returning EINTR. In normal
usage, a signal is blocked using sigblock(3), to begin a
critical section, variables modified on the occurrence of
the signal are examined to determine that there is no work
to be done, and the process pauses awaiting work by using
sigpause with the mask returned by sigblock.
