Checking The Users Server Role

I would like to determine if a particular user has sysadmin server
role. Is there a way to do this via the connection string? Currently
our code checks if a login is valid using SQLDriverConnect, however we
need to be certain that the user can login and modify the schema.

Is it possible to fetch a user's server role to determine if it has a
sysadmin server role?Look for the IS_SRVROLEMEMBER function in Books Online.
