C SPECIFICATION

       Bool glXIsDirect( Display *dpy,
                         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,
       bypassing the X server.  Nondirect rendering contexts pass all  render-
       ing commands to the X server.

ERRORS

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