NAME
      XtGetGC, XtReleaseGC - obtain and destroy a sharable GC

SYNTAX
      GC XtGetGC(w, value_mask, values)
            Widget w;
            XtGCMask value_mask;
            XGCValues *values;

      void XtReleaseGC(w, gc)
            Widget w;
            GC gc;

ARGUMENTS
      gc        Specifies the GC to be deallocated.

      values    Specifies the actual values for this GC.

      value_mask
                Specifies which fields of the values are specified.

      w         Specifies the widget.

DESCRIPTION
      The XtGetGC function returns a sharable, read-only GC.  The parameters to
      this function are the same as those for XCreateGC except that a widget is
      passed instead of a display.  XtGetGC shares only GCs in which all values
      in the GC returned by XCreateGC are the same.  In particular, it does not
      use the value_mask provided to determine which fields of the GC a widget
      considers relevant.  The value_mask is used only to tell the server which
      fields should be filled in with widget data and which it should fill in
      with default values.  For further information about value_mask and
      values, see XCreateGC in the Xlib - C Language X Interface.

      The XtReleaseGC function deallocate the specified shared GC.
