USTL!  

You have access to the raw socket via the connection handle.  It's just a
SMP to cast it to the right type, grab the descriptor, and write(2) your
packet.  Is that what you're looking for?  

Cf. INIT_HDBC in src/odbc/odbc.c:121.  You will find that 

HDBC is a TDS_DBC*
is a    struct _hdbc* that
has a   TDSSOCKET* named tds_socket that
is a    struct tds_socket* that 
has a   TDS_SYS_SOCKET named s that

is probably just an int in tds_sysdep_public.h.  

If there's a blessed ODBC way, I don't know about it.

Sure.  The rest of the code is mostly comments and filler, as you can see.

HTH.
