strsignal(3) -- Linux man page
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
This function is not part of any standard, but may be found on Linux
systems and some UNIX systems (such as Solaris).
