psignal, sys_siglist - system signal messages
psignal() produces a short message on the standard error file describ-
ing 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.
