-/**

- * Wait for a specified refresh count.  This implements most of the

- * functionality of \c glXWaitForMscOML from the GLX_OML_sync_control spec.

- * Waits for the \c target_msc refresh.  If that has already passed, it

- * waits until \f$(MSC \bmod divisor)\f$ is equal to \c remainder.  If 

- * \c target_msc is 0, use the behavior of glXWaitVideoSyncSGI(), which

- * omits the initial check against a target MSC value.

- * 

- * This function is actually something of a hack.  The problem is that, at

- * the time of this writing, none of the existing DRM modules support an

- * ioctl that returns a 64-bit count (at least not on 32-bit platforms).

- * However, this function exists to support a GLX function that requires

- * the use of 64-bit counts.  As such, there is a little bit of ugly

- * hackery at the end of this function to make the 32-bit count act like

- * a 64-bit count.  There are still some cases where this will break, but

- * I believe it catches the most common cases.

- *

- * The real solution is to provide an ioctl that uses a 64-bit count.

- *

- * \param dpy         Pointer to the \c Display.

- * \param priv        Pointer to the DRI drawable private.

- * \param target_msc  Desired refresh count to wait for.  A value of 0

- *                    means to use the glXWaitVideoSyncSGI() behavior.

- * \param divisor     MSC divisor if \c target_msc is already reached.

- * \param remainder   Desired MSC remainder if \c target_msc is already

- *                    reached.

- * \param msc         Buffer to hold MSC when done waiting.

- *

- * \return            Zero on success or \c GLX_BAD_CONTEXT on failure.
