With Smart Alloc and Heap Walker, programmers can interactively explore the behavior of _fmalloc(), _ffree(), GlobalAlloc(), GlobalFree(), and _heapmin(). They can allocate memory either using GlobalAlloc() or _fmalloc(), or from a DLL. They can determine when and how memory is allocated easily, without recompiling.

The source code for Smart Alloc also demonstrates some interesting features. Smart Alloc is a multiple-instance, large-model application when compiled with Microsoft C/C++ version 7.0. Another interesting feature of Smart Alloc is that it includes a dynamic link library (DLL) that intercepts all calls SMART.EXE makes to GlobalAlloc(), GlobalReAlloc(), and GlobalFree().

Smart Alloc was built with Microsoft C/C++ version 7.0 and tested under Microsoft Windows version 3.1.
