| * \page page_pjlib_exception_test Test: Exception Handling |
| * |
| * This file provides implementation of \b exception_test(). It tests the |
| * functionality of the exception handling API. |
| * |
| * @note This test use static ID not acquired through proper registration. |
| * This is not recommended, since it may create ID collissions. |
| * |
| * \section exception_test_sec Scope of the Test |
| * |
| * Some scenarios tested: |
| * - no exception situation |
| * - basic TRY/CATCH |
| * - multiple exception handlers |
| * - default handlers |
| * |
| * |
| * This file is <b>pjlib-test/exception.c</b> |
