M glXMakeCurrent Errors • BadMatch is generated if drawable was not created with the same X screen and visual as ctx. It is also generated if drawable is None and ctx is not NULL. • BadAccess is generated if ctx was current to another thread at the time glXMakeCurrent was called. • GLXBadDrawable is generated if drawable is not a valid GLX drawable. • GLXBadContext is generated if ctx is not a valid GLX context. • GLXBadContextState is generated if glXMakeCurrent is executed between the execution of glBegin and the corresponding execution of glEnd. • GLXBadContextState is also generated if the rendering context current to the calling thread has GL renderer state GL_FEEDBACK or GL_SELECT. • GLXBadCurrentWindow is generated if there are pending GL commands for the previous context and the current drawable is a window that is no longer valid. • BadAlloc may be generated if the server has delayed allocation of ancillary buffers until glXMakeCurrent is called, only to find that it has insufficient resources to complete the allocation.
