BOOL wglGetGenlockSourceDelayI3D(HDC hDC, UINT *uDelay)
hDC - Device context for the frame lock card, or a window residing on the
frame lock card.
*uDelay - The delay, in pixels, from the sync source trigger edge to the
actual trigger pulse.
TRUE: Success
FALSE: Failure
BOOL wglQueryGenlockMaxSourceDelayI3D(HDC hDC,
hDC - Device context for the frame lock card, or a window residing on the
frame lock card.
*uMaxLineDelay - The maximum number of raster scan lines per frame.
This includes all visible and non-visible lines—such as
vertical blanking lines— for all fields.
*uMaxPixelDelay - The maximum number of pixels per raster scan
line. This includes all visible and non-visible pixels
such as horizontal blank.
TRUE: Success
FALSE: Failure
