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 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.
