I am doing some work with Smalltalk V/PM. In order to access functions in DLL's it is often necessary to know the ordinal number of a function as well as which library the function is located in. Is there a utility available which will list the contents of a .LIB file showing the ordinal number of each function and the DLL where the function is found? I was able to find some information by looking at a .LIB file with a hex editor but it would be easier if there was a way to simply dump the information. The listing I get from the LIB utility is insufficient. If there isn't a utility available does anyone know the format of .LIB files? James W.

You can use the LIB.EXE program to get the numbers you want. You need to determine which LIB goes with the DLL you want to get the ordinal numbers for. Then you simply execute LIB with that library and when asked for operations press return and then give a file name for the list file. Examine this list file and you will see a list of all functions in the library followed by another list of these functions with offsets and sizes. The position of the functions in the second list is the ordinal number. Hope that helps, Vance Kessler

The format as I understand it from looking at DLL's with a hex editor is: Function_name Ordinal_value Null Some_other_unknown_hex_value That's how I understand it from reverse engineering some of the DLL's I've written. Of course I could be wrong, but that's the way it seems to work out for me... -gerry -- uunet!dialogic!gerry | "Even a dead plant turns | Dialogic Corporation OR | over a new leaf | 300 Littleton Rd gerry@dialogic.UUCP | when the wind blows." | Parsippany, NJ 07054 | | (201)334-8450

Two things: 1) why do you feel you need the ordinal number, instead of
just the name? (I have only found a very limited set of cases where
this is true.) 2) I would recommend using the EXEHDR utility, which
is bundled with both Microsoft C 6.0 and the PM SDK. Then you just
type "exehdr <dllname>" and get a listing of all kinds of relevent
information. Alternatively, you can use the information provided in
the <exehdr.h> header file to read in the DLL yourself.
Hope this helps,
Mark

In order to access certain functions (mostly in DOSCALLS) the ordinal number is needed to access the function. The EXEHDR utility is not helpful for this problem. There are only a handful of functions whose names appear in the DLL. I've managed to use a hex editor on the os2.lib file and figure out where to get the ordinal number for a function. What I haven't been able to easily figure out is what the best way would be to dump the ordinal information from the os2.lib file into an easily read format. Someone has mentioned that the second part of a lib listing shows the functions in ordinal order. As long as there aren't any gaps in the assignment of ordinal numbers examining this list with an editor that shows line numbers would be one way to go. You mention a file called 'exehdr.h'. I have both the IBM PM Toolkit as well as the Microsoft toolkit (version 1.2 for both). I haven't found the file you mention. Where would I find this file? James W.

Well, I figured out a klugey kind of way, but it works!
Jim> Someone has mentioned that the second part of a lib listing shows

I'm not sure that's true.

Jim> numbers would be one way to go.
I wouldn't rely on that method, though. Here's what I did (it took a
few minutes):
1) created a file os2.lis from os2.lib using the LIB utility
2) using an Epsilon editor macro, for just the first set of routines
(which, by inspection of os2.lib, are the ones which reside in
DOSCALLS), I created matching C definitions and calls of the type
extern PASCAL FAR DOSCLOSE();
.
.
.
DOSCLOSE();
3) I put a main() and some other calls around these 400-odd DOS calls,
and then compiled and linked with the /MAP directive, producing a map
file, the important part of which I include below:
