55 // ------------------------------------------------------------------------
56 // Source Code Organization
58 // First, see pkgconf/uitron.h for details of applicable configuration
61 // This file uit_func.h provides prototypes for the uITRON API. All the
62 // uITRON functions are listed here. The prototypes are configurable
63 // either to have C or C++ linkage, and if being compiled in a C++
64 // environment, to be inline.
66 // The function prototypes are all in terms of uITRON type definitions from
67 // uit_type.h, which is included at the head of uit_func.h.
69 // The implementations of the uITRON functions are in uit_func.inl, which
70 // is either included at the end of uit_func.h (if functions are inline) or
71 // in uit_func.cxx (if outline).
73 // uit_func.cxx provides some startup functions plus, if the uITRON
74 // functions are out of line, uit_func.inl is included to instantiate those
77 // uITRON system objects (tasks, semaphores...) are described in
78 // uit_obj.hxx. This is a C++ file and is used by the implementation of
79 // the uITRON functions.
81 // The uITRON system objects are instantiated in uit_obj.cxx, which uses
82 // uit_obj.hxx to define the objects, and the configuration file
83 // pkgconf/uitron.h to construct them as required.
85 // The include graph from an application, which should only include
86 // uit_func.h, is similar to the following:
89 // [inline uITRON functions:]
92 // . uit_func.h ; prototypes for funcs
93 // . . pkgconf/uitron.h ; configuration info
94 // . . uit_type.h ; typedefs for func args
95 // . (function prototypes)
96 // . . uit_func.inl ; full function bodies
97 // . . . uit_objs.hxx ; defs of uITRON data
98 // . . (function implementations)
101 // [out-of-line uITRON functions:]
104 // . uit_func.h ; prototypes for funcs
105 // . . pkgconf/uitron.h ; configuration info
106 // . . uit_type.h ; typedefs for func args
107 // . (function prototypes)
110 // [other uITRON compilation units:]
112 // uit_func.cxx ; out-of-line functions
113 // . pkgconf/uitron.h ; configuration info
114 // . uit_func.h ; prototypes for funcs
115 // . . uit_type.h ; typedefs for func args
116 // . (function prototypes)
117 // . . uit_func.inl ; full function bodies
118 // . . . uit_objs.hxx ; defs of uITRON data
119 // . . (function implementations)
122 // uit_objs.cxx ; static uITRON data objects
123 // . pkgconf/uitron.h ; configuration info
124 // . uit_objs.hxx ; defs of uITRON data
125 // (static uITRON system objects)
128 // The various include files are protected against multiple inclusion and
129 // so may be safely re-included as convenient.

147 // of, or for use by a pure C program, or of course outlined in C++ for
148 // Code size reasons.
154 // THEN functions must be C linkage and out of line:
155 // do NOT specify CYGIMP_UITRON_INLINE_FUNCS nor
156 // CYGIMP_UITRON_CPP_OUTLINE_FUNCS.
157 // IF compiling in C++
158 // THEN functions can be inline: specify CYGIMP_UITRON_INLINE_FUNCS
