sdlxGetRectUnionFloat function rect

SdlxFRect? sdlxGetRectUnionFloat(SdlxFRect a, SdlxFRect b)

Calculate the union of two rectangles with float precision.

\param A an SDL_FRect structure representing the first rectangle. \param B an SDL_FRect structure representing the second rectangle. \param result an SDL_FRect structure filled in with the union of rectangles A and B. \returns true on success or false on failure; call SDL_GetError() for more information.

\threadsafety It is safe to call this function from any thread.

\since This function is available since SDL 3.2.0.

extern SDL_DECLSPEC bool SDLCALL SDL_GetRectUnionFloat(const SDL_FRect *A, const SDL_FRect *B, SDL_FRect *result)
