strsignal - return string describing signal


   #include <string.h>

   char *strsignal(int sig);

   extern const char * const sys_siglist[];

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

       Since glibc 2.10:
           _POSIX_C_SOURCE >= 200809L
       Before glibc 2.10:


   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.


   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.
