//
// Author(s):   hmt
// Contributors:        hmt
// Date:        1998-03-13
// Purpose:     uITRON compatibility functions
// Description: 
//
//####DESCRIPTIONEND####
//
//===========================================================================
 
// ------------------------------------------------------------------------
// Source Code Organization
//
// First, see pkgconf/uitron.h for details of applicable configuration
// options.
//
// This file uit_func.h provides prototypes for the uITRON API.  All the
// uITRON functions are listed here.  The prototypes are configurable
// either to have C or C++ linkage, and if being compiled in a C++
// environment, to be inline.
//
// The function prototypes are all in terms of uITRON type definitions from
// uit_type.h, which is included at the head of uit_func.h.
//
// The implementations of the uITRON functions are in uit_func.inl, which
// is either included at the end of uit_func.h (if functions are inline) or
// in uit_func.cxx (if outline).
// 
// uit_func.cxx provides some startup functions plus, if the uITRON
// functions are out of line, uit_func.inl is included to instantiate those
// functions.
// 
// uITRON system objects (tasks, semaphores...) are described in
// uit_obj.hxx.  This is a C++ file and is used by the implementation of
// the uITRON functions.
// 
// The uITRON system objects are instantiated in uit_obj.cxx, which uses
// uit_obj.hxx to define the objects, and the configuration file
// pkgconf/uitron.h to construct them as required.
//
// The include graph from an application, which should only include
// uit_func.h, is similar to the following:
//
// 
// [inline uITRON functions:]
//
//    <your_app.c>
//    .       uit_func.h                       ; prototypes for funcs
//    .       .       pkgconf/uitron.h         ; configuration info
//    .       .       uit_type.h               ; typedefs for func args
//    .       (function prototypes)
//    .       .       uit_func.inl             ; full function bodies
//    .       .       .       uit_objs.hxx     ; defs of uITRON data
//    .       .       (function implementations)
//    
//
// [out-of-line uITRON functions:]
//
//    <your_app.c>
//    .       uit_func.h                       ; prototypes for funcs
//    .       .       pkgconf/uitron.h         ; configuration info
//    .       .       uit_type.h               ; typedefs for func args
//    .       (function prototypes)
//    
//
// [other uITRON compilation units:]
//
//    uit_func.cxx                             ; out-of-line functions
//    .       pkgconf/uitron.h                 ; configuration info
//    .       uit_func.h                       ; prototypes for funcs
//    .       .       uit_type.h               ; typedefs for func args
//    .       (function prototypes)
//    .       .       uit_func.inl             ; full function bodies
//    .       .       .       uit_objs.hxx     ; defs of uITRON data
//    .       .       (function implementations)
// 
//
//    uit_objs.cxx                             ; static uITRON data objects
//    .       pkgconf/uitron.h                 ; configuration info
//    .       uit_objs.hxx                     ; defs of uITRON data
//    (static uITRON system objects)
//
// 
// The various include files are protected against multiple inclusion and
// so may be safely re-included as convenient.

// IF compiling in C++
// THEN functions can be inline: specify CYGIMP_UITRON_INLINE_FUNCS
//   OR by default, functions are out of line:
//       outline functions can have C++ linkage:
//                 specify CYGIMP_UITRON_CPP_OUTLINE_FUNCS
//       OR by default, outline functions have C linkage.
