Hi,

I'm working my way thru the recently released book entitled
"The Design and Implementation of the 4.4BSD Operating System",
and have come across some algorithm code samples on pages 199 & 203:

disksort(dq, bp)
    drive queue *dq;
    buffer *bp;
{
    if (drive queue is empty) {
        place the buffer at the front of the drive queue;
        return;
    }
    if (request lies before the first active request) {
        locate the beginning of the second request list;
        sort bp into the second request list;
    } else
        sort bp into the current request list;
}

I'm familiar with the basics of c/c++, perl, shell scripts, but this
use of "the", "of", "into", "at" is something I've yet to see. It
seems a little too human readable to be real code.

What language is this?  Are there other examples of this type of
programming in the FreeBSD source code?

Thanks,
