PSIGNAL(3)                           BSD                            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 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 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.
