sdlxSaveFileIo function iostream

bool sdlxSaveFileIo(Pointer<SdlIoStream> src, Uint8List data, { bool closeio = false, })

Save all the data into an SDL data stream.

\param src the SDL_IOStream to write all data to. \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. \param closeio if true, calls SDL_CloseIO() on src before returning, even in the case of an error. \returns true on success or false on failure; call SDL_GetError() for more information.

\threadsafety Do not use the same SDL_IOStream from two threads at once.

\since This function is available since SDL 3.2.0.
