| michael@0 | 10 | // This file provides the plumbing to register functions to be executed |
| michael@0 | 11 | // as the main function of a child process in a multi-process test. |
| michael@0 | 12 | // This complements the MultiProcessTest class which provides facilities |
| michael@0 | 13 | // for launching such tests. |
| michael@0 | 14 | // |
| michael@0 | 15 | // The MULTIPROCESS_TEST_MAIN() macro registers a string -> func_ptr mapping |
| michael@0 | 16 | // by creating a new global instance of the AppendMultiProcessTest() class |
| michael@0 | 17 | // this means that by the time that we reach our main() function the mapping |
| michael@0 | 18 | // is already in place. |

| michael@0 | 21 | // MULTIPROCESS_TEST_MAIN(a_test_func) { |

| michael@0 | 23 | // return 0; |
