Bill, you've looked at it and arrived at a conclusion.  I trust your 
judgement.  I'm sure you won't duplicate code; where you find commonality, 
you'll use it.  

It does sound to me like db-lib is a subset of ct-lib (once again).  If 
libtds had a tds_blk_bind() that supported ct-lib's bidirectionality, db-lib 
could call it, but only one way.  

As a design objective, IMO all wire services handled in libtds.  By that, I 
mean most of the functions in read.c and write.c should be used only by 
libtds; the client libraries should use higher level abstractions, things 
that insulate them from endianism and protocol flavors.  I hope the rewrite 
will push those kinds of low-level decisions down from db-lib to libtds, and 
that we won't introduce more wire handling in ct-lib.  

Does that seem like a feasible, useful guideline to you?  

Do you still want me to add src/tds/bcp.c?
