Hmmmm. Dav's QBasic Site ( http://www.qbasicnews.com/dav/qb64.php ) has some tutorials/samples of making API calls in QB64. You might look at some of those.
Here's one that uses several API calls: http://www.qbasicnews.com/dav/files/dirinfo-api.bas
Another place to begin is in the wiki: https://qb64phoenix.com/qb64wiki/index.p..._Libraries
I'm still learning the all the QB64 esoterica, so I'm going to be tinkering with API calls myself.
