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 (ints, ...)
       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 (ints)
       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.
