large objects and libpq/++

Im running postgresql 6.5.1 on Suse linux. I 've got the database on a
seperate
machine to the shared library API I have written. I can connect and run
queries
with no problem but when i try to add a large object it fails in the
lo_open
function. I've called lo_creat before hand so thats not the problem.
When I
check in the server /usr/local/pgsql/data/base/<db>/ directory I can fnd
the
large object OID details eg xinv97697 xinvx97697. This is also confired
by
outputting the OID that was returned by lo_creat.

Normally when you create a large object. you can see it in psql by using
the \d
command. However you can't see them if you do this.

Any ideas? anyone?

cheers

libpq
libpq++ alterations with him.
