Subject: Calling Windows routines in djgpp
Message-ID: <BDFDFA7E18@fs2.mt.umist.ac.uk>

  (Oh no, groan, I'm raising this thread again.)
  In the course of trying to find how to write Windows programs in djgpp that
can create windows and menu boxes etc like Visual C does, I have waded at
length through several large expensive comprehensive-looking books on the
inner workings of Windows and I am at the end of what I can track down myself.
  (0) I have found that Windows functions are in a number of tables of them,
e.g. GetFilePortName is number 343 in the table USER, and that it is called as
`WORD FAR PASCAL GetFilePortName(LPOSFTRUCT) LPOFSTRUCT lpofstruct; (display a
"print to file" box and return the chosen file's details in arg `lpofstruct').
  (1) Where is FTP or WWW info about special interrupts that only work in
Windows?
  (2) Where on FTP or WWW is a full listing of these Windows functions (names,
arg patterns, what they do, what number position in which table)? The
information on (0) is from `Undocumented Windows', which does not describe
`documented' functions (documented where (including number and table name)?).
  (3) Please: If one of these functions is the n'th function in the table
QWERTY, and it has such and such an arg pattern, how do I call it from djgpp?
If someone could write an interface that will let a djgpp program start under
Windows (not in a DOS box) and call just one of these functions, say the
abovementioned GetFilePortName, I can (given a source of information (2)) do
the rest of the donkey work and make altered copies of GetFilePortName's
interface matter to call each of the many other such Windows functions.
