sdlxLoadFileIo function iostream

({Uint8List data, int datasize})? sdlxLoadFileIo(Pointer<SdlIoStream> src, { bool closeio = false, })

Load all the data from an SDL data stream.

The data is allocated with a zero byte at the end (null terminated) for convenience. This extra byte is not included in the value reported via datasize.

The data should be freed with SDL_free().

\param src the SDL_IOStream to read all available data from. \param datasize a pointer filled in with the number of bytes read, may be NULL. \param closeio if true, calls SDL_CloseIO() on src before returning, even in the case of an error. \returns the data or NULL 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.
