| /** |
| * cairo_debug_reset_static_data: |
| * |
| * Resets all static data within cairo to its original state, |
| * (ie. identical to the state at the time of program invocation). For |
| * example, all caches within cairo will be flushed empty. |
| * |
| * This function is intended to be useful when using memory-checking |
| * tools such as valgrind. When valgrind's memcheck analyzes a |
| * cairo-using program without a call to cairo_debug_reset_static_data(), |
| * it will report all data reachable via cairo's static objects as |
| * "still reachable". Calling cairo_debug_reset_static_data() just prior |
| * to program termination will make it easier to get squeaky clean |
| * reports from valgrind. |
| * |
| * WARNING: It is only safe to call this function when there are no |
| * active cairo objects remaining, (ie. the appropriate destroy |
| * functions have been called as necessary). If there are active cairo |
| * objects, this call is likely to cause a crash, (eg. an assertion |
| * failure due to a hash table being destroyed when non-empty). |
| * |
| * Since: 1.0 |
