Windows Runtime Unsupported CRT Functions

 

The new home for Visual Studio documentation is Visual Studio 2017 Documentation on docs.microsoft.com.

The latest version of this topic can be found at Windows Runtime Unsupported CRT Functions.

Many C run-time (CRT) APIs can’t be used in Windows 8.x Store apps that execute in the Windows Runtime. These apps are built by using the /ZW compiler flag. For a list of unsupported CRT functions, see CRT functions not supported by /ZW.

All CRT APIs are described in the Alphabetical Function Reference section of the documentation.
