psignal(3C)psignal(3C)NAME
psignal, psiginfo - system signal messages
SYNOPSIS
#include <siginfo.h>
void psignal (int sig, const char *s);
void psiginfo (siginfo_t *pinfo, const char *s);
DESCRIPTION
psignal and psiginfo produce messages on the standard error output
describing a signal. sig is a signal that may have been passed as the
first argument to a signal handler. pinfo is a pointer to a siginfo
structure that may have been passed as the second argument to an enhanced
signal handler [see sigaction(2)]. The argument string s is printed
first, then a colon and a blank, then the message 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>.
