- Remarks:
- -------
-
- - This has been compiled by Borland C++ 3.0 and MSC 7.0, not by Borland
- C++ 3.1 (It may very well work, but I do not have that version). Borland
- C++ 2.0 lacks a library function "_fullpath" used by MSWFILE.C.
-
- - If you want to compile this code but do not have a Windows 3.1 SDK (or
- Borland C++ 3.1, or Windows NT), you need to set the #define WIN30SDK to
- 1 in MSWIN.H. This will remove a few features (notably drag'n drop) but
- makes the sources compatible with the 3.0 WINDOWS.H.
-
- - This code has to be compiled in large model. Since, even in that
- model, Borland C++ and MSC 7.0 can generate a single Data Segment, it is
- still possible to run multiple instances of MEWIN. The other compilers
- may generate multiple data segments in large model, thus creating
- single-instance-only programs. Depending on the users' taste, this may
- be a non-issue due to MDI availability..
-
- - For Windows 3.x, the Borland C++ 3.0 and MSC 7.0 libraries provide a
- segment suballocator for the malloc, realloc and free functions. Other
- compilers often supply a simple segment allocator for those functions in
- large model. Since the maximum number of segments allocated at any time
- under Windows cannot exceed 8K (the number of entries in the selector
- table), use of a suballocation mechanism is a must. The MSWMEM.C module
- contains just that. A previous BETA of this program was compiled with BC
- 2.0 and therefore used this module, so it has been tested. However, I
- have encountered very rare occurences of UAEs that I believe are caused
- by MSWMEM.C. The MSWIN.H module contains flags SUBALLOC and MEMTRACE
- which should be set to 1 if you want to use malloc/realloc/free from
- MSWMEM.C. MEMTRACE is not absolutely necessary but adds a trace of the
- last 256 MSWMEM events. I had installed that to catch the UAE in the act
- with the help of DrFrank (a UAE dump taker/analyzer)... The thing has
- never reared its ugly head since then!
