NAME

       dsignal.h -

       Contains the API for serializing signals to a pipe for usage with
       select() or poll().

SYNOPSIS

   Functions
       int daemon_signal_init (int s,...)
           Installs signal handlers for the specified signals.
       int daemon_signal_install (int s)
           Install a signal handler for the specified signal.
       void daemon_signal_done (void)
           Free resources of signal handling, should be called before daemon
           exit.
       int daemon_signal_next (void)
           Return the next signal received.
       int daemon_signal_fd (void)
           Return the file descriptor the daemon should select() on for
           reading.

Detailed Description

       Contains the API for serializing signals to a pipe for usage with
       select() or poll().

       You should register all signals you wish to handle with select() in
       your main loop with daemon_signal_init() or daemon_signal_install().
       After that you should sleep on the file descriptor returned by
       daemon_signal_fd() and get the next signal received with
       daemon_signal_next(). You should call daemon_signal_done() before
       exiting.

       Definition in file dsignal.h.

Function Documentation

   void daemon_signal_done (void)
       Free resources of signal handling, should be called before daemon exit.

       Examples:
           testd.c.

   int daemon_signal_fd (void)
       Return the file descriptor the daemon should select() on for reading.
       Whenever the descriptor is ready you should call daemon_signal_next()
       to get the next signal queued.

       Returns:
           The file descriptor or negative on failure

       Examples:
           testd.c.

   int daemon_signal_init (int s,  ...)
       Installs signal handlers for the specified signals. Parameters:
           s,... The signals to install handlers for. The list should be
           terminated by 0

       Returns:
           zero on success, nonzero on failure

       Examples:
           testd.c.

   int daemon_signal_install (int s)
       Install a signal handler for the specified signal. Parameters:
           s The signalto install handler for

       Returns:
           zero onsuccess,nonzero on failure

   int daemon_signal_next (void)
       Return the next signal received. This function will not block. Instead
       it returns 0 if no signal is queued.

       Returns:
           The next queued signal if one is queued, zero if none is queued,
           negative on failure.

       Examples:
           testd.c.
