mismatch in formal parameter list

The formal parameter list of a function (or a pointer to a function) does not match those of another function (or pointer to a member function). As a result, the assignment of functions or pointers cannot be made.

The following sample generates C2563:

// C2563.cpp  
void func( int );  
void func( int, int );  
int main() {  
   void *fp();  
   fp = func;   // C2563  
}
