From: Emil Velikov <[email protected]>If the user provides an invalid display or device the ToVendor lookup will fail. In this case, the local [Mesa vendor] error code will be set. Thus on sequential eglGetError(), the error will be EGL_SUCCESS. To be more specific, GLVND remembers the last vendor and calls back into it's eglGetError, although there's no guarantee to ever have had one. v2: - Add _eglError call, so the debug callback is executed (Kyle) - Drop XXX comment.

That looks right to me. -Kyle _______________________________________________ mesa-dev mailing list [email protected] https://lists.freedesktop.org/mailman/listinfo/mesa-dev
