3.1 Errors

Where possible, as in X, when a request terminates with an error, the request has no side effects.

The error codes that may be generated by a request are described with that request. The following table summarizes the GLX-specific error codes that are visible to applications:

GLXBadContext A value for a Context argument does not name a Context.

GLXBadContextState An attempt was made to switch to another rendering context while the current context was in RenderMode GL _FEEDBACK or GL _SELECT, or a call to glXMakeCurrent was made between a glBegin and the corresponding call to glEnd.

GLXBadCurrentWindow The current Drawable of the calling thread is a window that is no longer valid.

GLXBadDrawable The Drawable argument does not name a Drawable configured for OpenGL rendering.

GLXBadPixmap The Pixmap argument does not name a Pixmap that is appropriate for OpenGL rendering.

The following error codes may be generated by a faulty GLX implementation, but would not normally be visible to clients:

GLXBadContextTag A rendering request contains an invalid context tag. (Context tags are used to identify contexts in the protocol.)

GLXBadRenderRequest A glXRender request is ill-formed.

GLXBadLargeRequest A glXRenderLarge request is ill-formed.

GLXUnsupportedPrivateRequest May be returned in response to either a glXVendorPrivate request or a glXVendorPrivateWithReply request.
