psignal(3)
Name
psignal, sys_siglist − system signal messages
Syntax
psignal(sig, s)
unsigned sig;
char *s;
char *sys_siglist[];
Description
The psignal subroutine 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.
