sdlSaveFile function iostream

bool sdlSaveFile(String? file, Pointer<NativeType> data, int datasize)

Save all the data into a file path.

\param file the path to write all available data into. \param data the data to be written. If datasize is 0, may be NULL or a invalid pointer. \param datasize the number of bytes to be written. \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.
