I am trying to program a game that was origianlly going to be for DOS until
I realised that my Turbo C/C++ compiler for Windows only compiled for windows.
Now, I have to find a way of using basic text windows or something to output
my text card game.
I thought I had found the perfect solution when I found functions like
cprintf and window and clrscr, etc. in the conio.h library however, they
won't work.

#include<conio.h>

int main(void)
{
	clrscr();
	window(10, 10, 20, 20);
	cprintf("Hello world\r\n");
	getch();
	return 0;
}

This program gives me these warnings and errors:
Warning WINDOW.C 6: Call to function 'window' with no prototype in function
main
Warning WINDOW.C 7: Call to function 'cprintf' with no prototype in function
main
Linker Error: Undefined symbol _cprintf in module WINDOW.C
Linker Error: Undefined symbol _window in module WINDOW.C

I think I have all my directories set up right, (all my other functions
work fine with calls to other libraries).

Might this have something to do with me running all this under Win95? Is there
something else I need to do to get these to work? I tried putting in
prototypes for these functions but that only got rid of the warnings.

Please help me....

Nick.
