Some of which I assume (although haven't checked) are part of the GLES* api. There is something funny especially since the same library provides eglGetProcAddress.
There are some (rather strange) suggestions on the web that the library can be used as a libEGL/libGLES* replacement. Thus I aimed my earlier comment as - there is not point for mesa to attempt to provide all the functions listed by the Catalyst. Hope ^^ came out less patronising than usual :-) Cheers, Emil _______________________________________________ mesa-dev mailing list mesa-dev@lists.freedesktop.org http://lists.freedesktop.org/mailman/listinfo/mesa-dev
