       signals(D5)                                              signals(D5)


       NAME
             signals - signal numbers

       SYNOPSIS
             #include <sys/signal.h>
             #include <sys/ddi.h>

       DESCRIPTION
             There are two ways to send a signal to a process.  The first,
             psignal(D3),  or, on multiprocessor systems, proc_signal(D3),
             can be used by non-STREAMS drivers.  The second, by using an
             M_SIG or M_PCSIG message, can be used by STREAMS drivers and
             modules.

             The following is a list of the signals that drivers may send
             to processes.

             SIGHUP      The device has been disconnected.

             SIGINT      The interrupt character has been received.

             SIGQUIT     The quit character has been received.

             SIGPOLL     A pollable event has occurred.

             SIGTSTP     Interactive stop of the process.

             SIGURG      Urgent data are available.

             SIGWAITING  All LWPs in a process are blocked.

             SIGWINCH    The window size has changed.

       USAGE
             The signal SIGTSTP cannot be generated with psignal or
             proc_signal.  It is only valid when generated from a stream.
