 NAME
      pause - suspend process until signal

 SYNOPSIS
      #include <&lt&lt&lt;unistd.h>&gt&gt&gt;

      int pause(void);

 DESCRIPTION
      pause() suspends the calling process until it receives a signal.	The
      signal must be one that is not currently set to be ignored or blocked
      (masked) by the calling process.

      If the signal causes termination of the calling process, pause() does
      not return.

      If the signal is caught by the calling process and control is returned
      from the signal-catching function (see signal(5)), the calling process
      resumes execution from the point of suspension; with a return value of
      -1 from pause() and errno set to EINTR.

 WARNING
      Check all references to signal(5) for appropriateness on systems that
      support sigvector(2).  sigvector() can affect the behavior described
      on this page.

 APPLICATION USAGE
    Threads Considerations
      Signal dispositions (such as catch/default/ignore) are shared by all
      threads in the process and blocked signal masks are maintained by each
      thread.  Therefore, the signals being waited for should not be ignored
      by the process or blocked by the calling thread.

      pause() will suspend only the calling thread until it receives a
      signal.

      If other threads in the process do not block the signal, the signal
      may be delivered to another thread in the process and the thread in
      pause() may continue waiting.  For this reason, the use of sigwait()
      is recommended instead of pause() for multi-threaded applications.

      For more information regarding signals and threads, refer to
      signal(5).
