###### (This is the legacy documentation for stable SDL2, the current stable version; [SDL3](https://wiki.libsdl.org/SDL3/) is the current development version.) # SDL_HapticNumEffects Get the number of effects a haptic device can store. ## Header File Defined in [SDL_haptic.h](https://github.com/libsdl-org/SDL/blob/SDL2/include/SDL_haptic.h) ## Syntax ```c int SDL_HapticNumEffects(SDL_Haptic * haptic); ``` ## Function Parameters | | | | -------------- | -------------------------------------------- | | **haptic** | the [SDL_Haptic](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](SDL_GetError)() for more information. ## Remarks 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](SDL_HapticNumEffects)(). ## Version This function is available since SDL 2.0.0. ## See Also * [SDL_HapticNumEffectsPlaying](SDL_HapticNumEffectsPlaying) * [SDL_HapticQuery](SDL_HapticQuery) ---- [CategoryAPI](CategoryAPI), [CategoryAPIFunction](CategoryAPIFunction)
