psignal(3)              (BSD Compatibility Package)              psignal(3)


   NAME
         psignal, syssiglist - system signal messages

   SYNOPSIS
         cc [ flag... ] file ... -lucb

         psignal(sig, s)
         unsigned sig;
         char *s;

         char *syssiglist[];

   DESCRIPTION
         psignal produces a short message on the standard error file
         describing the indicated signal.  First the argument string s is
         printed, then a colon, then the name of the signal and a NEWLINE.
         Most usefully, the argument string is the name of the program which
         incurred the signal.  The signal number should be from among those
         found in <signal.h>.

         To simplify variant formatting of signal names, the vector of message
         strings syssiglist is provided; the signal number can be used as an
         index in this table to get the signal name without the newline.  The
         define NSIG defined in <signal.h> is the number of messages provided
         for in the table; it should be checked because new signals may be
         added to the system before they are added to the table.
