###### (This is the legacy documentation for SDL2, the previous stable version; [SDL3](https://wiki.libsdl.org/SDL3/) is the current stable version.) # SDL_GetAssertionReport Get a list of all assertion failures. ## Header File Defined in [SDL_assert.h](https://github.com/libsdl-org/SDL/blob/SDL2/include/SDL_assert.h) ## Syntax ```c const SDL_AssertData * SDL_GetAssertionReport(void); ``` ## Return Value (const [SDL_AssertData](SDL_AssertData) *) Returns a list of all failed assertions or NULL if the list is empty. This memory should not be modified or freed by the application. ## Remarks This function gets all assertions triggered since the last call to [SDL_ResetAssertionReport](SDL_ResetAssertionReport)(), or the start of the program. The proper way to examine this data looks something like this: ```c const SDL_AssertData *item = SDL_GetAssertionReport(); while (item) { printf("'%s', %s (%s:%d), triggered %u times, always ignore: %s.\\n", item->condition, item->function, item->filename, item->linenum, item->trigger_count, item->always_ignore ? "yes" : "no"); item = item->next; } ``` ## Version This function is available since SDL 2.0.0. ## See Also - [SDL_ResetAssertionReport](SDL_ResetAssertionReport) ---- [CategoryAPI](CategoryAPI), [CategoryAPIFunction](CategoryAPIFunction), [CategoryAssert](CategoryAssert)
