| 56 // Source Code Organization | |
| 57 // | |
| 58 // First, see pkgconf/uitron.h for details of applicable configuration | |
| 59 // options. | |
| 60 // | |
| 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. | |
| 65 // | |
| 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. | |
| 68 // | |
| 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). | |
| 72 // | |
| 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 | |
| 75 // functions. | |
| 76 // | |
| 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. | |
| 80 // | |
| 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. | |
| 84 // | |
| 85 // The include graph from an application, which should only include | |
| 86 // uit_func.h, is similar to the following: | |
| 87 // | |
| 88 // | |
| 89 // [inline uITRON functions:] | |
