Agreed, but the rationale of the page is to document topics that are helpful when using the APIs. And, as I noted already stuff like 'void *' is borerline, but I think it's helpful to have some info summarized in one place. And, additionally, POSIX adds a detail to the C standard (casting between void * and function pointer). By the way, thanks for all of your input so far. Among other things, it made me realize that some navigational corrections were needed.
