Detours
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.
Detours users will appreciate increased robustness in application programming interfaces (APIs) that start a process with a DLL containing detour functions. Detours also preserves the uninstrumented target function (callable through a trampoline) as a subroutine for use by the instrumentation. This trampoline design enables a large class of innovative extensions to existing binary software.
Software developers can use Detours to create an automatic distributed partitioning system. Developers and architects can also use this technology to instrument and analyze the DCOM protocol stack, and to create a thunking layer for a COM-based OS API.
