Detailed Description

This is an abstract base class for wglGraphicsPipe and wdxGraphicsPipe; that is, those graphics pipes that are specialized for working with Microsoft Windows.

There isn't much code here, since most of the fancy stuff is handled in WinGraphicsWindow. You could make a case that we don't even need a WinGraphicsPipe class at all, but it is provided mainly for completeness.

Member Function Documentation

◆ lookup_cpu_data()

void WinGraphicsPipe::lookup_cpu_data ( )
virtual

Looks up the detailed CPU information and stores it in _display_information, if supported by the OS.

This may take a second or two.

Reimplemented from GraphicsPipe.
