Example of remote DB access via ESQL/C

Hello all! I was wondering if anyone could share an example of connecting an ESQL/C program to a remote DB server. What requirements are there? Do the libs have to be on the same computer as the program? Do you need to compile the ESQL source on the same machine as the server, or on the one it will be running on, or does it even matter? Do the Env vars need to be set? A simple example would be really helpful! Thanks, -Tim
