Windows Runtime Unsupported CRT Functions

Visual Studio 2012

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

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