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.
|
||
|

||

|
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.
