NAME

       XtGetGC, XtReleaseGC - obtain and destroy a sharable GC

SYNTAX

       #include <X11/Intrinsic.h>

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

       void XtReleaseGC(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.
