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.
