Name MESA_release_buffers Name Strings GLX_MESA_release_buffers Contact Brian Paul (brian 'at' mesa3d.org) 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 ancilliary 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 accum- ulation 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 ancilliary 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. Revision History 8 June 2000 - initial specification
