Compiler Error C2129

static function 'function' declared but not defined

A forward reference is made to a static function that is never defined.

A static function must be defined within file scope. If the function is defined in another file, it must be declared extern.

The following sample generates C2129:

// C2129.cpp
static void foo();   // C2129

int main() {
   foo();
}

Possible resolution:

// C2129b.cpp
static void foo();

int main() {
   foo();
}

static void foo() {}
