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.
