wglJoinSwapGroupNV(), glxJoinSwapGroupNV()

This call adds the OpenGL window with the device context hDC to the swap group speciﬁed by group. If hDC is already a member of a different group, it is implicitly removed from that group ﬁrst.

Function	B00L JoinSwapGroupNV (HDC hDC, GLuint group);
Parameters In	hDC - Device context for the frame lock card, or a
	window residing on the frame lock card.
	group - Swap group number to which the device
	context is to be assigned.
	The value must be between 0 and maxGoups
	(see wglQueryMzxSwapGroupsNV (),
	glxyQueryMaxSwapGroupsNV ()
Parameters Out	N/A

Return Values	TRUE: Success
	FALSE: Failure

wglBindSwapBarrierNV(),

glxBindSwapBarrierNV()

This call binds a swap group to a barrier.

Function	B00L BindSwapBarrierNV (GLuint group, GLuint
	barrier);

Parameters In	hDC - Device context for the frame lock card, or a
	window residing on the frame lock card.
	group - Swap group number that is bound to a
	barrier.
	barrier - Barrier number to which the swap group
	is to be bound. Value must be between 0 and
	maxBarrier
	(see wglQueryMzxSwapGroupsNV (),
	glxyQueryMaxSwapGroupsNV ()
Parameters Out	N/A

Return Values	TRUE: Success
	FALSE: Failure
