The fact that SQLAllocHandle returns SQL_ERROR indicates a problem
before the connection is even attempted.
I think the function you want is SQLGetDiagRec.
If you have access to a Windows machine, download the latest Microsoft
Data Access SDK and look at its ODBC documentation. If not, try
searching for SQLAllocHandle on ibm.com; they have pretty good
documentation for their DB2 ODBC driver, which conforms to ODBC
standards, such as they are. In any case, you need some documentation,
because ODBC is a complicated beast.
If you're flexible about which API to use, I always recommend db-lib as
the best documented and easiest to use. YMMV, of course.
