SDL_SeekIO - Seek within an SDL_IOStream

       This function is available since SDL 3.2.0.

       This function seeks to byte offset , relative to whence .  whence may be any of the following values:

       • SDL_IO_SEEK_SET : seek from the beginning of data

       • SDL_IO_SEEK_CUR : seek relative to current read point

       • SDL_IO_SEEK_END : seek relative to the end of data

       If this stream can not seek, it will return -1.

context
              a pointer to an SDL_IOStream
               structure.

       offset an offset in bytes, relative to whence location; can be negative.

       whence any of SDL_IO_SEEK_SET , SDL_IO_SEEK_CUR , SDL_IO_SEEK_END .
