Printf statement not working inside GLfunctions

I'm not able to print the values of variables inside a opengl function(for debugging purposes).

Printf statement works perfectly but it prints either zero or some junk value.

ex:
xcur,ycur-global varables

window_display()
.......
printf("values of %3.2f %3.2f", &xcur,&ycur);
.....

same type of statements not working in keyboard function and other functions

Is there any special setting or special function to do that?

thanks & regards

You're passing a pointer to the variables to printf as opposed to the variables themselves. You have

printf(..., &xcur, &ycur);

it should be

printf(..., xcur, ycur);

Perhaps you got confused with scanf, which does require you to pass pointers?

If that code example is from your code, then it has problems, because that code above is trying print pointers as floats. Simple get rid of those &'s and it should work fine, assuming those variables really are floats of some type.

scanf. And you're right, no &'s in printf.

oh god, thanks guys.Actually I'm kinda confused since i started using opengl.

once again, thanks guys
