A library to assist in dealing with exceptions and errors in C/C++ Windows Applications

Author: MSDN.WhiteKnight (

License: BSD 3-clause

Requirements: Windows Vista or newer, Visual Studio 2012+ (VS 2015+ or NuGet 3.3+ for NuGet package)


  • Simple way to get exception code, error message and stack trace in the handler block for SEH exceptions (as well as unhandled C++ exceptions which cause them)
  • Executing user-defined callback function on unhandled SEH exception
  • Helper macros for converting Win32/COM errors into exceptions
  • Configurable logging: can write diagnostic information into log file, stderr stream, Windows Event Log or other targets
  • Multithreaded: all functionality can be used from different threads independently
  • All string processing in Unicode (wide characters)


Include ErrLib.h in one of more of your modules and have fun using ErrLib functions (see below)!


  • ErrLib dynamically links to Visual C++ 2012 Standard Library (CRT) - debug or release depending on version. This means, either target machines must have Visual C++ 2012 Redistributable installed, or you must redistribute its DLLs along with your application. For any other deployment option, rebuid project from sources, changing configuration accordingly.
  • You can use ErrLib via LoadLibrary/GetProcAddress if you really want, but don't call FreeLibrary. Unloading ErrLib before process termination is not supported.
  • Enable full debug information in Visual Studio 2017 and above for complete stack traces (/DEBUG:FULL in linker options).
