sdlRWtell function

int sdlRWtell(
  1. Pointer<SdlRWops> context
)

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

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

Prior to SDL 2.0.10, this function was a macro.

\param context a SDL_RWops 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.

\since This function is available since SDL 2.0.10.
