sigpause(3BSD)       (BSD System Compatibility)       sigpause(3BSD)


       NAME
             sigpause - (BSD) automatically release blocked signals and
             wait for interrupt

       SYNOPSIS
             /usr/ucb/cc [flag . . . ] file . . .
             sigpause(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 indicate 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(3BSD), 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.
