I.5 Notes for Netware platforms

There doesn't appear to have been any interest in the Netware version of mpatrol and as a result I will not be implementing any of the following features (or fixing any of the following problems) in mpatrol for Netware. I don't even have access to a Netware machine so someone else would have had to have done it anyway.

• The library has not yet been built (let alone tested) on Netware platforms. The names of the system functions that the library calls for Netware were obtained by looking at Novell's developer documentation, so they may not even compile correctly without modification.

• Need to add support for building the mpatrol library as an NLM. This is not currently a high priority requirement as the archive library should suffice for most purposes. However, if it is built as an NLM and malloc() and related functions are dynamically linked in some executable files then perhaps it would be possible to override these functions, thus getting the `--dynamic' option in the mpatrol command to work.

• Need to add support for processors other than the Intel 80x86. However, about 99% of Netware platforms run on this processor family -- does anyone really use Netware with other processors?

• Need to add way to determine when the base of the stack has been reached during call stack traversal, since on Netware every application is really a thread running under one large process.

• Need to add support for reading symbols from Netware load modules. Also need to add support for reading symbols from any NLMs that are required by the program. This may be possible in a limited fashion by using the GNU BFD library, but may only work with code compiled with gcc.

• Could add support for the `EDIT' and `LIST' options. This would probably involve finding a way to invoke a batch file without having to search for the batch file or allocating memory in the process.

• Add GUI support for the mptrace command.

• Need to investigate if it is safe (or even possible) to override the definitions of malloc(), etc., without including the `mpatrol.h' header file first. Currently, non-macro definitions for these functions have been disabled in the Netware version of the library in case they affect other NLMs that are currently running.
