Windows Development Library for twinBASIC - API Coverage

This is a partial list of the current API coverage of WinDevLib.

Broad overview of feature coverage

  • Shell interfaces and APIs including shell automation and Property System
  • COM and OLE foundations including type library interfaces
  • General purpose APIs from common system DLLs like user32, kernel32, gdi32, ole32, oleaut32, etc.
  • General purpose Native APIs from ntdll.
  • Common Controls APIs and Common Dialog APIs; UI Ribbon; UI Animation
  • DirectX technologies, from 8-12, including most extended features only from the DirectX SDK
  • OpenGL, including full coverage beyond the Windows SDK through v4.6 with ARB, EXT, and vendor-specific functions.
  • Windows Media Foundation
  • CoreAudio/WASAPI, XAudio2, XACT3
  • XInput
  • Windows Imaging Component (WIC), GDIPlus
  • WINMM.dll multimedia, timer, and joystick APIs
  • Microsoft Speech API
  • Image Color Management / Windows Color System API
  • Windows cryptography and certificate APIs, including both older APIs like crypt32.dll and CNG APIs bcrypt and ncrypt.
  • Security-related APIs like LSA and Authz
  • Accessibility, UI Automation, and IME
  • Configuration Manager and SetupAPI; WIM; Software Licensing; Package Manager (OPC)
  • Radio Manager, Sensor and Location APIs, Bluetooth APIs, Portable Devices API
  • Windows Media Device Manager
  • Windows Filtering Platform
  • WebView2
  • Internet APIs including Winsock, WinInet, WinHttp, WinDNS, WNet, HTTP server, IPHLPAPI, websocket, urlmon, hlink, traffic management, WLAN, and various system COM interfaces.
  • Local network APIs (netapi32)
  • Active Directory
  • Human Interface Device APIs (HID)
  • Winspool
  • Debug APIs (dbghlp, imagehlp)
  • Background Intelligent Transfer Service (BITS)
  • Virtual Disk Service (VDS)
  • Low-level SQL APIs
  • Windows Terminal Services
  • Low-level WMI
  • ActiveScript; Uniscribe
  • Windows Biometric Framework
  • SmartCard APIs
  • Event Tracing for Windows (ETW)
  • Group Policy
  • Filter Manager
  • Cloud filter APIs
  • UPNP Automation
  • Windows Remote Management (WSMAN) low-level API

This is not a complete list and numerous minor features are covered or part of what I just listed as 'general purposes'.

SDK Header Coverage

This is a work in progress and not complete! Additional headers may be covered but not listed.

Note: Header file list is from the Windows 11 26000 SDK. Some header files are from other SDKs like the DirectX SDKs or other Microsoft SDKs or publications.

  • Verified 100% basic coverage (for SDK 10.0.22621.0 minimum, most for 10.0.26100.0);
    Excluded from completed %:

    • Definitions unsupported by the tB language with no reasonable substitute.
    • Definitions disabled by conditional compilation with version flags for XP and earlier, non-Windows platforms, or kernel mode only.

    Basic Coverage: excludes macros, callbacks->delegates, ANSI APIs (though most are covered), and other headers from #include statements.
    Anything else missing is a bug and a report should be filed\
