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:
	       _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), NULL may instead be returned for an invalid
       signal number.
