Never mind, I figured it out.
For anyone else who's curious:
-------- start snippet ------------------
global integer callWindowsHelp, libHtmlHelp
-- register the HTML Help library
libHtmlHelp = registerw32Library("hhctrl.ocx")
-- get an id for the HtmlHelpA routine in hhctrl.ocx.
callWindowsHelp = registerw32Function(libHtmlHelp, "HtmlHelpA", {C_INT,
C_INT, C_INT, C_INT}, C_INT)
-- a sample calling routine:
procedure LetsCallWinHelp(sequence FileName, -- help file name
atom command, -- type of help needed
atom data) -- value related to type of command
atom file_ptr, start
-- how to pass messages to the help engine !!
file_ptr = acquire_mem(0, FileName)
start = w32Func(callWindowsHelp, {getHandle(myWindow), file_ptr,
command, data})
release_mem(file_ptr)
end procedure
-- and it's called like this:
LetsCallWinHelp("my_help_file.chm", #0002, 0)
Note: When calling WinHelpA(), the command value for viewing the help
TOC was #0003, but in HtmlHelpA() it's #0002.

Hmmm, I had figured out a different way.
I'll give this one a shot, too.
Thanks, Ken!

I suppose .chm and .hlp formats are proprietary, and the Unix man
format is pretty obsolete.
Why not just call system("konqueror file://index.html",0) to start
the browser and use HTML docs?

I don't think so, but it would depend on whether or not someone has
reverse-engineered compiled HTML. I know there are de-compilers that
work under windows, but whether or not you can get your hands on source
is something I _don't_ know.

This, I really doubt unless there's a utility I don't know about that
reads winhelp format under UNIX. This is quite possible; there are
lots of utilities for reading what I thought were Windows-only formats.
The best I can do is wish you luck.

In HTML Workshop version 4.74.8702.0 (from Microsoft) use
File/decompile. I just tried it on refman2.chm and it spit out 42 source
files (.htm, .gif, as well as a .hhk and a .hhc).

I don't know - look here, and decide for yourself:

Well, I use them also, but many state that they are "no longer
maintained". And you'll have to admit that man pages lack a lot
when compared to html.

You can convert chm to standard html format which does not require a
proprietary viewer: http://chm2web.aklabs.com/ (free trial period)
However, the most interesting use of .chm files is to distribute
trojans. See:
