SYNOPSIS

     #include <signal.h>

     int
     sigpause(int sigmask);

DESCRIPTION

     This interface is made obsolete by sigsuspend(2).

     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 to be blocked.
     Sigpause() always terminates by being interrupted, returning -1 with
     errno set to EINTR
