Chapter 8 Tool Helper Library

The tool helper library (TOOLHELP.DLL) makes it easier for developers who work with the Microsoft Windows 3.1 operating system to obtain system information and control system activity. This dynamic-link library was designed to streamline the creation of Windows-hosted tools, specifically Windows-hosted debugging applications. TOOLHELP.DLL is available to applications running with Windows versions 3.0 and later.

To use the elements of TOOLHELP.DLL in an application, you must include the TOOLHELP.H header file in the application source files, link the application with TOOLHELP.LIB, and ensure that TOOLHELP.DLL is in the system path.
