Detours is a library for instrumenting arbitrary Win32 functions on x86, x64, and IA64 machines. Detours intercepts Win32 functions by rewriting the in-memory code for target functions. The Detours package also contains utilities to attach arbitrary dynamic-link libraries (DLLs) and data segments (called payloads) to any Win32 binary.
