In the page you mentioned:

 Format of a C decorated name
The form of decoration for a C function depends on the calling convention used in its declaration, as shown in the following table. It's also the decoration format that's used when C++ code is declared to have extern "C" linkage. The default calling convention is __cdecl. **In a 64-bit environment, C or extern "C" functions are only decorated when using the __vectorcall calling convention**.
