Get the number of effects a haptic device can store.


int SDL_HapticNumEffects(SDL_Haptic * haptic);

Function Parameters

haptic the SDL_Haptic device to query

Return Value

Returns the number of effects the haptic device can store or a negative error code on failure; call SDL_GetError() for more information.


On some platforms this isn't fully supported, and therefore is an approximation. Always check to see if your created effect was actually created and do not rely solely on SDL_HapticNumEffects().


This function is available since SDL 3.0.0.
