Function declarators

Function declarators consist of the following elements:

• An identifier, or name
• Parameter declarations, which specify the parameters that can be passed to the function in a function call
• Exception declarations, which include throw expressions; exception specifications are described in Exception handling (C++ only).
• The type qualifiers const and volatile, which are used only in class member functions; they are described in Constant and volatile member functions (C++ only).
