GLXContext ctx )

PARAMETERS
       dpy  Specifies the connection to the X server.

       ctx  Specifies the GLX context that is being queried.

DESCRIPTION
       glXIsDirect  returns  True  if  ctx is a direct rendering context, False
       otherwise.  Direct rendering contexts pass rendering  commands  directly
       from  the  calling  process's address space to the rendering system, by‐
       passing the X server.  Nondirect rendering contexts pass  all  rendering
       commands to the X server.

ERRORS
       GLXBadContext is generated if ctx is not a valid GLX context.
