     NAME
          XSGIMiscQueryExtension - determine whether miscellaneous SGI
          extension functions are supported

     SYNTAX
          #include <X11/extensions/SGIMisc.h>

          Bool XSGIMiscQueryExtension(
            Display *display,
            int *event_base,
            int *error_base
          )

     DESCRIPTION
          The XSGIMisc extension to the X Window System adds
          miscellaneous SGI-specific functions.

          XSGIMiscQueryExtension returns True if the XSGIMisc
          extension is supported on the specified display.  If the
          extension is supported, the value of the first event code
          associated with the extension is returned in event_base and
          the value of the first error code associated with the
          extension is returned in error_base.
