NAME

       XtGetClassExtension - locate a class extension record

SYNOPSIS

       XtPointer XtGetClassExtension(object_class, byte_offset type, version, record_size)
	       WidgetClass object_class;
	       Cardinal byte_offset;
	       XrmQuark type;
	       long version;
	       Cardinal record_size;

ARGUMENTS

       Specifies  the  widget class containing the extension list to be searched.  Specifies the offset in bytes form the base of the widget class
       of the extension field to be searched.  Specifies the name of the class extension to be located.  Specifies the minimum acceptable  version
       of  the class extension required for a match.  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 widget_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.
       XtGetClassExtension 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 modified by the widget class owner.
