DESCRIPTION

XDisplayHeight∗() returns an integer that describes the height of the screen in pixels.  XDisplayHeightMM() returns the height of the specified screen in millimeters. 

The C language macros DisplayHeight() and DisplayHeightMM() are equivalent and slightly more efficient. 

These functions are misnamed; they should really be XScreenHeight() and XScreenHeightMM().
