   You'll have to forgive me if this question is too easy I'm a C
   beginner, but any it has to do with srand.

   To seed the random number table I always used srand(time(NULL)).
   I have both time.h and stdlib.h included. Djgpp refuses to accept
   this line of code. Is there any other way to do this?

   I download some programs hoping to find this answer but most
   of them had a randomize() function which Djgpp doesnt seem to touch
   and one of them even querried the user for the seed!

   Maybe this could be put in the faq?


The function time() returns a (time_t).  Simply cast it to an (unsigned int)
which is what srand() expects, hence:

	srand((unsigned int)time( (time_t *)NULL ));

BTW: Please no one get on my case about the cast of the NULL.  We've been over
that already.
