The C Runtime is being refactored…
Note CRT is being refactored. The implementation is split into different modules. Read more here: http://blogs.msdn.com/b/vcblog/archive/2014/06/10/the-great-crt-refactoring.aspx
Relevant excerpt from above blog post:
In order to unify these different CRTs, we have split the CRT into three pieces:
- VCRuntime (vcruntime140.dll): This DLL contains all of the runtime functionality required for things like process startup and exception handling, and functionality that is coupled to the compiler for one reason or another. We mayneed to make breaking changes to this library in the future.
- AppCRT (appcrt140.dll): This DLL contains all of the functionality that is usable on all platforms. This includes the heap, the math library, the stdio and locale libraries, most of the string manipulation functions, the time library, and a handful of other functions. We will maintain backwards compatibility for this part of the CRT.
- DesktopCRT (desktopcrt140.dll): This DLL contains all of the functionality that is usable only by desktop apps. Notably, this includes the functions for working with multibyte strings, the exec and spawn process management functions, and the direct-to-console I/O functions. We will maintain backwards compatibility for this part of the CRT.
