This command locks the backbuffer and stores the backbuffer details for direct access.

LOCK BACKBUFFER

This command does not return a value.

The backbuffer is the actual screen you see each refresh and this command allows you to pass the pointer and other essential data to a DLL for screen modification. Locking the backbuffer prevents other activities to be performed to the backbuffer, so it is essential you unlock the backbuffer when you have finished.
