You should use the function SQLDisconnect:

SQLDisconnect
Conformance
Version Introduced: ODBC 1.0
Standards Compliance: ISO 92
Summary
SQLDisconnect closes the connection associated with a specific connection
handle.
Syntax
SQLRETURN SQLDisconnect(
     SQLHDBC     ConnectionHandle);
Arguments
ConnectionHandle
[Input]
Connection handle.
Returns
SQL_SUCCESS, SQL_SUCCESS_WITH_INFO, SQL_ERROR, or SQL_INVALID_HANDLE.

This is one of the things that's defined in the file, but it isn't wrapped
at all--and that you should really use if you're writing an ODBC app.  I'd
recommend writing a disconnect procedure that closes the connection and then
frees the connection handle.

This is a good example of the rest of the work that needs to be done before
someone incorporates it into a serious project.

You can check out MSDN for the full API docs (that's what I've been using):


If you want to connect with a connect string, take a look at
SQLDriverConnect
