psignal(3)             C LIBRARY FUNCTIONS             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.
