NAME
     XtGetClassExtension - locate a class extension record

     #include <X11/Intrinsic.h>

     XtPointer	XtGetClassExtension(WidgetClass object_class, Cardinal byte_off-
	    set, XrmQuark type, long version, Cardinal record_size);

ARGUMENTS
     object_class
	       Specifies the widget class containing the extension  list  to  be
	       searched.

     byte_offset
	       Specifies  the  offset in bytes form the base of the widget class
	       of the extension field to be searched.

     type      Specifies the name of the class extension to be located.

     version   Specifies the minimum acceptable version of the	class  extension
	       required for a match.

     record_size
	       Specifies  the  minimum	acceptable length of the class extension
	       record required for match, or 0.

DESCRIPTION
     The list of extension records at the specified offset in the specified wid-
     get_class will be searched for a match on the  specified  type,  a  version
     greater  than  or equal to the specified version, and a record size greater
     than or equal the specified record_size  if  it  is  nonzero.   XtGetClass-
     Extension	returns  a  pointer to a matching extension record or NULL if no
     match is found.  The returned extension record is owned by the widget class
     and must not be modified or freed by the caller, except possibly to be mod-
     ified by the widget class owner.
