clearviewport function
I need help with viewports!
am using C v.2.01 under windows XP. Part of my C program code defines a viewport. A later part of the program clears the viewport then the device is also cleared. A drawpoly follows the two routine. The problem is that only a part of the polygon is visible. It appears that the polygon is inscribed in a screen dimension that was actually previously defined as the viewport. Could it be that the viewport still exists? If so, how can i reset the display back to full screen.
