XT FUNCTIONS                             XtGetClassExtension(3xt)



NAME
     XtGetClassExtension - locate a class extension record

SYNTAX
     cc [ flag... ] file... -lXt [ library... ]

     XtPointer XtGetClassExtension(WidgetClass object_class, Car-
          dinal byte_offset, XrmQuark type, long version, Cardi-
          nal record_size);

ARGUMENTS
     object_class
               Specifies the widget class containing the exten-
               sion 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 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.  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 modified by the
     widget class owner.
