sdlTellIo function iostream

int sdlTellIo(Pointer<SdlIoStream> context)

Determine the current read/write offset in an SDL_IOStream data stream.

SDL_TellIO is actually a wrapper function that calls the SDL_IOStream's seek method, with an offset of 0 bytes from SDL_IO_SEEK_CUR, to simplify application development.

\param context an SDL_IOStream data stream object from which to get the current offset. \returns the current offset in the stream, or -1 if the information can not be determined.

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

\since This function is available since SDL 3.2.0.
