NAME
strsignal - return string describing signal
SYNOPSIS
#define _GNU_SOURCE
#include <string.h>
char *strsignal(int sig);
extern const char * const sys_siglist[];
DESCRIPTION
The
strsignal()
function returns a string describing the signal
number passed in the argument sig.
The string can only be used
until the next call to
strsignal().
The array sys_siglist holds the signal description strings
indexed by signal number.
The
strsignal()
function should be
used if possible instead of this array.
RETURN VALUE
The
strsignal()
function returns the appropriate description
string, or an unknown signal message if the signal number is invalid.
On some systems (but not on Linux), a NULL pointer may be
returned instead for an invalid signal number.
CONFORMING TO

Present on Solaris and the BSDs.
