libdvdcss again

[Gildas Bazin]

Hi,

As libdvdcss api is working with blocks (sectors) instead of bytes, I was just thinking that it would maybe make more sense to change the specification for dvdcss_readv a little bit.

Instead of having iovec structures where the iov_len field is the length in BYTES of the iovbase buffer, iov_len could be the length in BLOCKS (or sectors) of the buffer.

This would make things a little bit more coherent.

And not to confuse people we could use the following prototype:
int dvdcss_readv( dvdcss_handle, void *p_iovec, int i_buffers, int i_flags );

I think it make sense to do everything in BLOCKS as anyway this library is designed to work only on DVDs.

Regards,
