+
+Status
+
+ Shipping since Mesa 2.0 in October, 1996.
+
+Version
+
+ Last Modified Date: 8 June 2000
+
+Number
+
+ 217
+
+Dependencies
+
+ OpenGL 1.0 or later is required.
+ GLX 1.0 or later is required.
+
+Overview
+
+ Mesa's implementation of GLX is entirely implemented on the client side.
+ Therefore, Mesa cannot immediately detect when an X window or pixmap is
+ destroyed in order to free any ancillary data associated with the window
+ or pixmap.
+
+ The glxMesaReleaseBuffers() function can be used to explicitly indicate
+ when the back color buffer, depth buffer, stencil buffer, and/or accumu-
+ lation buffer associated with a drawable can be freed.
+
+IP Status
+
+ Open-source; freely implementable.
+
+Issues
+
+ None.
+
+New Procedures and Functions
+
+ Bool glXReleaseBuffersMESA( Display *dpy, GLXDrawable d );
+
+New Tokens
+
+ None.
+
+Additions to Chapter 3 of the GLX 1.3 Specification (Functions and Errors)
+
+ The function
+
+ Bool glXReleaseBuffersMESA( Display *dpy, GLXDrawable d );
+
+ causes all software ancillary buffers (back buffer, depth, stencil,
+ accum, etc) associated with the named drawable to be immediately
+ deallocated. True is returned if <d> is a valid Mesa GLX drawable,
+ else False is returned. After calling glXReleaseBuffersMESA, the
+ drawable should no longer be used for GL rendering. Results of
+ attempting to do so are undefined.
+
+
+GLX Protocol
+
+ None, since this is a client-side operation.
+
+Errors
+
+ None.
+
+New State
+
+ None.
