Compiler Warning (level 1) C4630

'symbol' : 'extern' storage class specifier illegal on member definition

Remarks

A data member or member function is defined as extern. Members cannot be external, although entire objects can. The compiler ignores the extern keyword.

Example

The following example generates C4630:

// C4630.cpp
// compile with: /W1 /LD
class A {
   void func();
};

extern void A::func() {   // C4630, remove 'extern' to resolve
}
