sdlSeekIo function

int sdlSeekIo(
  1. Pointer<SdlIoStream> context,
  2. int offset,
  3. int whence
)

Seek within an SDL_IOStream data stream.

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.

\param context a pointer to an SDL_IOStream structure. \param offset an offset in bytes, relative to whence location; can be negative. \param whence any of SDL_IO_SEEK_SET, SDL_IO_SEEK_CUR, SDL_IO_SEEK_END. \returns the final offset in the data stream after the seek or -1 on failure; call SDL_GetError() for more information.

\since This function is available since SDL 3.1.3.
