expected formal parameter list, not a type list
A function definition contains a parameter type list instead of a formal parameter list. ANSI C requires formal parameters to be named unless they're void or an ellipsis (...).
An example of a named formal parameter is the int i in void func(int i).
A parameter type list is a list of types, for example, int, char.
The following code generates error C2055:
// C2055.c
// compile with: /c
void func(int, char) {} // C2055
void func (int i, char c) {} // OK
