There is no complete function, variable or API reference for the Half-Life SDK or engine.

You have to figure things out on your own by trial and error, find some other Half-Life source code or tutorial that does something similar, or ask someone a question about how to do something on one of the Half-Life coding forums (or here).

Everybody else learns things by seeing what other people had done and by experimenting with new things on their own.
