SDL_GetAssertionHandler

Get the current assertion handler.

Header File

Syntax

SDL_AssertionHandler SDL_GetAssertionHandler(void **puserdata);

Function Parameters

puserdata

pointer which is filled with the "userdata" pointer that was passed to SDL_SetAssertionHandler()

Return Value

Returns the SDL_AssertionHandler that is called when an assert triggers.

Remarks

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().

The parameter puserdata is a pointer 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.

Version

This function is available since SDL 2.0.2.
