Compiler Error C2381

Error Message

'function' : redefinition; __declspec(noreturn) differs

A function was declared and then defined but the definition used the noreturn __declspec modifier. The use of noreturn constitutes a redefinition of the function; the declaration and definition need to agree on the use of noreturn.

The following sample generates C2381:

// C2381.cpp
// compile with: /c
void f1();
void __declspec(noreturn) f1() {}   // C2381
void __declspec(noreturn) f2() {}   // OK
