:> There is a long as a parameter to ccdbuffer that needs to be a u_long.
:> Otherwise, you'll get panics (can't remember where).
:> Basically, bcount needs to be a u_long in all cases.

:Que? Are you sure? That means you want to change struct buf, where
:b_bcount is declared as long, as well?

:Ciao,
:Sheldon.

    Absolutely not.  The maximum size of a struct buf is 64K or 128K or
    something like that.  b_bcount is fine the way it is.  There could
    be a problem with people *using* b_bcount in a complex expression and
    not casting it higher, but there is no problem with the structural
    field itself.
