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). **/ void cairo_debug_reset_static_data (void) { CAIRO_MUTEX_INITIALIZE (); _cairo_font_face_reset_static_data (); #if CAIRO_HAS_FT_FONT _cairo_ft_font_reset_static_data (); #endif _cairo_scaled_font_reset_static_data (); _cairo_pattern_reset_static_data (); CAIRO_MUTEX_FINALIZE (); }
