sdlxLoadFile function iostream

({Uint8List data, int datasize})? sdlxLoadFile(String file)

Load all the data from a file path.

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 file the path to read all available data from. \param datasize if not NULL, will store the number of bytes read. \returns the data or NULL 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.
