__DRIdrawableRec Struct Reference

#include <dri_interface.h>

---

Detailed Description

This structure is initialized during the __DRIscreenRec::createDrawable call. createDrawable is not called by libGL at this time. It's currently used via the dri_util.c utility code instead.

Data Fields
void(*	destroyDrawable )(__DRInativeDisplay *dpy, void *drawablePrivate)
	Method to destroy the private DRI drawable data.
int(*	frameTracking )(__DRInativeDisplay *dpy, void *drawablePrivate, GLboolean enable)
	Enable or disable frame usage tracking.
int(*	getSBC )(__DRInativeDisplay *dpy, void *drawablePrivate, int64_t *sbc)
	Get the number of completed swap buffers for this drawable.
void *	private
	Opaque pointer to private per drawable direct rendering data.
void *	private
	Opaque pointer to private per drawable direct rendering data.
int(*	queryFrameTracking )(__DRInativeDisplay *dpy, void *drawablePrivate, int64_t *sbc, int64_t *missedFrames, float *lastMissedUsage, float *usage)
	Retrieve frame usage information.
unsigned	swap_interval
	Used by drivers that implement the GLX_SGI_swap_control or GLX_MESA_swap_control extension.
void(*	swapBuffers )(__DRInativeDisplay *dpy, void *drawablePrivate)
	Method to swap the front and back buffers.
int64_t(*	swapBuffersMSC )(__DRInativeDisplay *dpy, void *drawablePrivate, int64_t target_msc, int64_t divisor, int64_t remainder)
	Like swapBuffers, but does NOT have an implicit glFlush.
int(*	waitForMSC )(__DRInativeDisplay *dpy, void *drawablePriv, int64_t target_msc, int64_t divisor, int64_t remainder, int64_t *msc, int64_t *sbc)
	Wait for the MSC to equal target_msc, or, if that has already passed, the next time (MSC % divisor) is equal to remainder.
int(*	waitForSBC )(__DRInativeDisplay *dpy, void *drawablePriv, int64_t target_sbc, int64_t *msc, int64_t *sbc)
	Wait for the SBC to be greater than or equal target_sbc.

void(* __DRIdrawableRec::swapBuffers)(__DRInativeDisplay *dpy, void *drawablePrivate)	(	__DRInativeDisplay *	dpy,
		void *	drawablePrivate
	)

int64_t(* __DRIdrawableRec::swapBuffersMSC)(__DRInativeDisplay *dpy, void *drawablePrivate, int64_t target_msc, int64_t divisor, int64_t remainder)	(	__DRInativeDisplay *	dpy,
		void *	drawablePrivate,
		int64_t	target_msc,
		int64_t	divisor,
		int64_t	remainder
	)

Once rendering is complete, waits until MSC is equal to target_msc, or if that has already passed, waits until (MSC % divisor) is equal to remainder. If divisor is zero, the swap will happen as soon as MSC is greater than or equal to target_msc.

Internal API version 20030317.

int(* __DRIdrawableRec::waitForMSC)(__DRInativeDisplay *dpy, void *drawablePriv, int64_t target_msc, int64_t divisor, int64_t remainder, int64_t *msc, int64_t *sbc)	(	__DRInativeDisplay *	dpy,

		int64_t	target_msc,
		int64_t	divisor,
		int64_t	remainder,

		int64_t *	sbc
	)

If divisor is zero, the function will return as soon as MSC is greater than or equal to target_msc.
