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 argument 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.
