## Detailed Description

Drawable dependent methods. 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.

## Member Data Documentation

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

Method to destroy the private DRI drawable data.

int(* __DRIdrawableRec::frameTracking)(__DRInativeDisplay *dpy, void *drawablePrivate, GLboolean enable)

Enable or disable frame usage tracking.

Since:
  Internal API version 20030317.

int(* __DRIdrawableRec::getSBC)(__DRInativeDisplay *dpy, void *drawablePrivate, int64_t *sbc)

Get the number of completed swap buffers for this drawable.

Since:
  Internal API version 20030317.

void * __DRIdrawableRec::private

Opaque pointer to private per drawable direct rendering data. `NULL` if direct rendering is not supported on the display or screen used to create this drawable. Never dereferenced in libGL.

int(* __DRIdrawableRec::queryFrameTracking)(__DRInativeDisplay *dpy, void *drawablePrivate, int64_t *sbc, int64_t *missedFrames, float *lastMissedUsage, float *usage)

Retrieve frame usage information.

Since:
  Internal API version 20030317.

unsigned __DRIdrawableRec::swap_interval

Used by drivers that implement the GLX_SGI_swap_control or GLX_MESA_swap_control extension.

Since:
  Internal API version 20030317.

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

Method to swap the front and back buffers.

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

Like `swapBuffers`, but does NOT have an implicit `glFlush`. 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.

Since:
  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)

Wait for the MSC to equal target_msc, or, if that has already passed, the next time (MSC % divisor) is equal to remainder. If divisor is zero, the function will return as soon as MSC is greater than or equal to target_msc.

Since:
  Internal API version 20030317.

int(* __DRIdrawableRec::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.

Since:
  Internal API version 20030317.
