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 descrip
tion 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
This function is not part of any standard, but may be
found on Linux systems and some UNIX systems (such as
Solaris).
