Description

XDisplayWidth*() returns an integer that describes the width of the screen in pixels.  XDisplayWidthMM() returns the width of the specified screen in millimeters.  The C language macros DisplayWidth() and DisplayWidthMM() are equivalent and slightly more efficient.  These functions are misnamed; they should really be XScreenWidth() and XScreenWidthMM().
