UnderHook v0.2 Released

UnderHook is a 32-bit x86 non-virtual function hooker. The library has the ability to dynamically intercept arbitrary function calls in precompiled binaries in execution and reroute them to a number of user defined functions.

----------

UnderHook version 0.2 has been released. This is a beta release.

Several bugs have been fixed in this release and there should be little trouble getting it to work with Windows this time around. To be sure of it, I have included a precompiled Win32 DLL in a separate downloadable package.

Updates include decoding of new opcodes meaning more functions can be hooked, correcting the parameter list when calling the original function (first parameter was previously incorrect), MSVC compilation issues, and more.

This release also includes example source demonstrating how to intercept calls to strcmp() and reroute them to strcmp_nocase(), a user-defined case insensitive string comparison function.

As always, documentation is available at http://uhook.net/api.htm

Enjoy!
