Is it possible to substitute system functions, as is possible on Linux and Solaris using the LD_PRELOAD
For example by setting the environment variable: LD_PRELOAD=/path/to/mymalloc.so
I would have my replacement malloc functions instead of in the C runtime already installed in the system libraries. All other functions in the system dll's would run as normal.
Microsoft Research has a library called Detours which allows you to intercept Win32 API calls.
Detours is a library for instrumenting arbitrary Win32 functions on x86, x64, and IA64 machines. Detours intercepts Win32 functions by re-writing the in-memory code for target functions. The Detours package also contains utilities to attach arbitrary DLLs and data segments (called payloads) to any Win32 binary.
If Detours ( as mentioned previously ) is not an option - then you might take a look at WinAPI Override. It is actively mantained. Note that only 32 bit version is available.
