Subj : Problem with my usage of conio.h

Please excuse the ignorance as I'm fairly new to C/C++. I'm writing a
simple program to print a screen-wide frame of astericks and put text
inside of that from the command line.

My issue comes in getting the screensize. I read online that conio.h
had a function called screensize() in it. I cound't find it but I did
find a function called gettextinfo() that returns a struct containing
screenheight and screenwidth. So I decided to attempt writing a wrapper
function to get them.
(Excuse the complexness, but for me to learn a new language, I have to
push myself to use stuff that may or may not be quite pointless!)

I'm running the free compiler (v5.5) on WinXP SP2.

Can someone please inform me as to why this is not working? All details
follow

Thanks in advance

Here is the code in question:
/* imports */
#include <stdio.h>
#include <conio.h>

/* The structure */
struct screen_size
{
unsigned char x;
unsigned char y;
};

/* function definition */
screen_size screensize();

/* the code in question (wrapped into a main()) */
int main()
{
struct screen_size ss;
ss = screensize();
printf("(%d,%d)",ss.x,ss.y);
return 0;
}

screen_size screensize()
{
struct text_info* ti;
struct screen_size ss;

gettextinfo(ti);

ss.x = (ti.screenwidth);
ss.y = (ti.screenheight);

return ss;
}





The errors I'm getting with this abbreviated code:
