    This is not how you ask a question on Stack Overflow. See [how to ask a good question](http://stackoverflow.com/help/how-to-ask), at least, before you ask. –  Nov 10 '15 at 08:28

These C API functions all have individual reference pages in the SICStus Prolog Manual. The C code in the libraries can probably serve as examples of their use.

In general you should avoid the C API, if possible, since it is so easy to do the wrong thing.
