XtGetGC(3Xt)                         SysV                         XtGetGC(3Xt)



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.
