Linux 2.6 - man page for strsignal (linux section 3)

STRSIGNAL(3)			    Linux Programmer's Manual			     STRSIGNAL(3)

NAME
       strsignal - return string describing signal

SYNOPSIS
       #include <string.h>

       char *strsignal(int sig);

       extern const char * const sys_siglist[];

   Feature Test Macro Requirements for glibc (see feature_test_macros(7)):

       strsignal():
	   Since glibc 2.10:
	       _XOPEN_SOURCE >= 700 || _POSIX_C_SOURCE >= 200809L
	   Before glibc 2.10:
	       _GNU_SOURCE

DESCRIPTION
       The strsignal() function returns a string describing the signal number passed in the argu-
       ment sig.  The string can be used only 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
       POSIX.1-2008.  Present on Solaris and the BSDs.
