Free outputdebugstring software for windows

DebugView intercepts calls made to DbgPrint by device drivers and OutputDebugString made by Win32 programs DebugView is a small software that will let you monitor debug output on your local system, or any computer on the network that you can reach via TCP/IP.
It is capable of displaying both kernel-mode and Win32 debug output, so you dont need a debugger to catch the debug output your applications or device drivers generate, nor do you need to modify your applications or drivers to use non-standard debug output APIs.
DebugView Capture
Under Windows 95, 98, and Me DebugView will capture output from the following sources:
- Win32 OutputDebugString
- Win16 OutputDebugString
- Kernel-mode Out_Debug_String
- Kernel-mode _Debug_Printf_Service
Under Windows NT, 2000, XP, Server 2003 and Vista DebugView will capture:
- Win32 OutputDebugString
- Kernel-mode DbgPrint
- All kernel-mode variants of DbgPrint implemented in Windows XP and Server 2003
Installation and Use
Simply execute the DebugView program file (dbgview.exe) and DebugView will immediately start capturing debug output. To run DebugView on Windows 95 you must get the WinSock2 update from Microsoft. Note that if you run DebugView on Windows NT/2K/XP you must have administrative privilege to view kernel-mode debug output. Menus, hot-keys, or toolbar buttons can be used to clear the window, save the monitored data to a file, search output, change the window font, and more. The on-line help describes all of DebugViews features.

StraceNT (pronounced S-Trace-NT) is a System Call Tracer for Windows. It provides similar functionality as strace provides on Linux. It can trace all the calls made by a process to the imported functions from other DLLs.
StraceNT can be very useful in debugging and analyzing the internal working of a program. It records function names, their arguments and their return value.
StraceNT uses IAT patching technique to trace function calls, which is quite reliable and very efficient way for tracing. StraceNT can handle functions with different calling conventions including __fastcall and __stdcall.
StraceNT also supports filtering based on DLL name and function name and gives you a lot of control on which calls to trace and helps you to easily isolate a problem.
Main features:
- A very fast and efficient system call tracing program
- Supports tracing function calls with different calling conventions
- Excellent filtering support to isolate a problem easily
- Freeware
- Similar in functionality to strace on Linux
- Multithreaded application supported
- Records OutputDebugString output of the target process
- Trace functions calls made to DLLs loaded dynamically using LoadLibrary
- Allows user to specify a different return value from a function
- Comes in both Graphical UI and command line version
-
Enhancements:
- Added tracing of DLLs which are loaded dynamically using LoadLibrary
- Added option for returning a different value from a function
- Made a GUI version of StraceNT also
- Modified inclusion/exclusion to provide much better filtering control
- Support is added for tracing functions exported by Ordinal
