Strace NT

StraceNT is a simple and lightweight tool that you can use to debug and analyze the internal functioning of an application. Using the IAT patching method, it can trace function calls for any running process.

Although not intended for beginners, the program is intuitive and provides a simple and clean interface, displaying information about currently traced processes and details regarding the initialized calls, together with the function names, arguments and their return values.

StraceNT attaches itself to any of the running processes to read information about the way it works and provides support for multiple calling conventions, such as the 'stdcall', 'cdecl' and 'fastcall' functions. It can successfully handle multi-threaded applications and offers full control over the tracing process.

One of the advantages of the program is the filtering capabilities, based on the DLL and the function name. Optionally, you can trace the function calls initiated by the main program executable only, specify the module that implements the function or the calling modules to be traced or excluded from the analysis. Choosing which calls to trace and which not allows you to easily detect and isolate a process functioning problem.

Users have the possibility to change the return value for a function and the program records the 'OutputDebugString' of the target process. The tracing results can be saved to your computer for later reference.

Besides the easy to use graphical interface, the application also includes a command line version, that advanced users can use for printing out a trace of all the system calls made by a process.

StraceNT is a handy tool that can help you understand how an application actually works, offering you an insight of the corresponding processes.
