Changes DepthCompareMode.(KMVERTEXBUFFDESC Structure)

Prototype declaration:


KMSTATUS KMAPI
kmChangeContextDepthCompareMode(
        IN OUT  PKMVERTEXBUFFDESC   pVertexBuffDesc,
        IN      KMDEPTHMODE         nDepthCompareMode
);

Description:

This function changes the rendering parameter DepthCompareMode that was registered in pGlobalParam
from pVertexBuffDesc by kmSetVertexRenderState/kmSetStripHead.
The following is a list of supported VertexType:

Note:
    This function changes some of pGlobalParam from pVertexBuffDesc before starting
    a strip in response to kmStartVertexStrip.  Operation is not guaranteed if the
    rendering parameters are not registered from pVertexBuffDesc to pGlobalParam
    within the same pass beforehand.

VertexType04 VertexType10 VertexType16
VertexType05 VertexType11 VertexType17
Parameters:
pVertexBuffDesc(input/output)
        This parameter is a pointer to KMVERTEXBUFFDESC.

nDepthCompareMode(input)
        This parameter specifies the DepthCompareMode setting.
