how to use ODBC interface

Hello,

I have installed Postgresql 7.1.3 on solaris 2.8.
I want to use ODBC interface of postgresql for applications that
will run mainly on SOLARIS.

1) Is there any example using ODBC interface e.g., using ODBC from a C/C++
application?

2)Is it more stable to use psqlODBC  or OpenLink ODBC postgresql odbc driver?
What are the advantage or disadvantages between these two drivers?

Thanks in advance,
Sofia Alexaki
