sigpause(3)        UNIX System V(BSD Compatibility Package)         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 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(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.
