◆ SDL_GetAssertionHandler()

SDL_AssertionHandler SDL_GetAssertionHandler ( void **  puserdata)

Get the current assertion handler.

This returns the function pointer that is called when an assertion is triggered. This is either the value last passed to SDL_SetAssertionHandler(), or if no application-specified function is set, is equivalent to calling SDL_GetDefaultAssertionHandler().

Parameters
puserdataPointer to a void*, which will store the "userdata" pointer that was passed to SDL_SetAssertionHandler(). This value will always be NULL for the default handler. If you don't care about this data, it is safe to pass a NULL pointer to this function to ignore it.
Returns
The SDL_AssertionHandler that is called when an assert triggers.

Definition at line 431 of file SDL_assert.c.

432 {
433  if (userdata != NULL) {
434  *userdata = assertion_userdata;

436  return assertion_handler;
437 }

References assertion_handler, assertion_userdata, and NULL.

◆ SDL_GetAssertionReport()

const SDL_assert_data* SDL_GetAssertionReport ( void  )

Get a list of all assertion failures.

Get all assertions triggered since last call to SDL_ResetAssertionReport(), or the start of the program.

The proper way to examine this data looks something like this:

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; }

Returns
List of all assertions.

◆ SDL_GetDefaultAssertionHandler()

SDL_AssertionHandler SDL_GetDefaultAssertionHandler ( void  )

Get the default assertion handler.

This returns the function pointer that is called by default when an assertion is triggered. This is an internal function provided by SDL, that is used for assertions when SDL_SetAssertionHandler() hasn't been used to provide a different function.

Returns
The default SDL_AssertionHandler that is called when an assert triggers.

◆ SDL_SetAssertionHandler()

void SDL_SetAssertionHandler ( SDL_AssertionHandler  handler,
void userdata 
)

Set an application-defined assertion handler.

This allows an app to show its own assertion UI and/or force the response to an assertion failure. If the app doesn't provide this, SDL will try to do the right thing, popping up a system-specific GUI dialog, and probably minimizing any fullscreen windows.

This callback may fire from any thread, but it runs wrapped in a mutex, so it will only fire from one thread at a time.

Setting the callback to NULL restores SDL's original internal handler.

This callback is NOT reset to SDL's internal handler upon SDL_Quit()!

Return SDL_AssertState value of how to handle the assertion failure.

Parameters
handlerCallback function, called when an assertion fails.
userdataA pointer passed to the callback as-is.
