How use wglAllocateMemoryNV?

The NVsdk say DrawElements/DrawArrays Using wglAllocateMemoryNV(size,0,0,1) is very fast,for use the Video Memory.But did not give a sample. Can somebody tell me how to use,or give me some code about this.All reply is appreciated.

Suggest you download Display3DS which includes the glext.h and wglext.h headers needed as well as legible code to see how it’s done.

Specifically, check out the Mesh3DS class constructor/destructor and header file for guidance.
