PSIGNAL(3)

NAME
psignal, sys_siglist - system signal messages

SYNOPSIS
#include <sys/signal.h>
void
psignal(unsigned sig, const char *s);
extern char *sys_siglist[];

DESCRIPTION
The psignal() function locates the descriptive message string for the given signal sig number and writes it to the stderr.

If the argument s is non-NULL it is written to the stderr prior to the message string. The signal number should be from among those found in <signal.h>.

The message strings can be accessed directly using the external character array sys_siglist. The defined variable NSIG contains a count of the messages in sys_siglist.

sigaction(2), perror(3)

HISTORY
The psignal() function appeared in 4.2BSD.
