57
// First, see pkgconf/uitron.h for details of applicable configuration
58
// options.
59
//
60
// This file uit_func.h provides prototypes for the uITRON API.  All the
61
// uITRON functions are listed here.  The prototypes are configurable
62
// either to have C or C++ linkage, and if being compiled in a C++
63
// environment, to be inline.
64
//
65
// The function prototypes are all in terms of uITRON type definitions from
66
// uit_type.h, which is included at the head of uit_func.h.
67
//
68
// The implementations of the uITRON functions are in uit_func.inl, which
69
// is either included at the end of uit_func.h (if functions are inline) or
70
// in uit_func.cxx (if outline).
71
// 
72
// uit_func.cxx provides some startup functions plus, if the uITRON
73
// functions are out of line, uit_func.inl is included to instantiate those
74
// functions.
75
// 
76
// uITRON system objects (tasks, semaphores...) are described in
77
// uit_obj.hxx.  This is a C++ file and is used by the implementation of
78
// the uITRON functions.
79
// 
80
// The uITRON system objects are instantiated in uit_obj.cxx, which uses
81
// uit_obj.hxx to define the objects, and the configuration file
82
// pkgconf/uitron.h to construct them as required.
83
//
84
// The include graph from an application, which should only include
85
// uit_func.h, is similar to the following:
