psignal(3)         UNIX System V(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.
