Tcl Windows API V2.2 overview


The Tcl Windows API (TWAPI) extension provides access to functions in the Windows API from within the Tcl scripting language. The TWAPI 2.x series supports Windows 2000 and later versions. For Windows NT 4.0 (SP3 or later), use TWAPI 1.1.5 or earlier releases.

The extension provides access to the Windows API at two levels:

  • a raw interface to the supported Windows API is provided where the Tcl commands directly map to Windows functions. Programmers who are familiar with the Win32 API and prefer to do things the hard way may prefer to use this interface.
  • a more convenient and powerful higher level interface that makes the API much more accessible. This is the interface documented in the remaining sections.
