Way to retrieve current resolution

Recommended Posts

OpenGl does not have a function for that(that I know of) but most OS''s have a function for it if you are using Win32 which most people are you
would write something like GetSystemMetrics (SM_CXSCREEN) to get the screen width and to get the screen hight you would use GetSystemMetrics(SM_CYSCREEN) Dont know how to do it without using a OS function. Hope that helps.
