   There are no stupid questions except for the one's whose
   answers embarrass me! 
   Check the mid() function in SNIPPETS. There is a whole suite
   of BASIC-like string handling functions in there.
   The following example allocates memory for the substring
   being returned, and that memory must eventually be returned
   to the OS or it will constitute a memory leak.
#include 
#include 
#include 
char *extract_substring(char *S, int from, int bytes)
{
   char *mid = malloc(bytes + 1);
   if(NULL != mid)
   {
      memmove(mid, S + from, bytes);
      mid[bytes] = (char)'\0';
   }
   return mid;
}
int main(void)
{
   char base_string[] = "Example String... Serves no purpose.";
   char *substring;
   substring = extract_substring(base_string, 8, 9);
   if(NULL == substring)
   {
      puts("Malloc error in extract_substring().");
      return 1;
   }
   puts("substring should be equal to \"String...\"");
   printf("substring = \"%s\".\n", substring);
   free(substring);
   return 0;
}
