    PSIGNAL(3)	    UNIX Programmer's Manual	       PSIGNAL(3)

    NAME
         psignal, sys_siglist - system signal messages

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

         char *sys_siglist[];

    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 new-line.  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 sys_siglist is provided; the signal
         number can be used as an index in this table to get the sig-
         nal 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.
