Function-Call Operator

A postfix-expression followed by the function-call operator, ( ), specifies a function call. The arguments to the function-call operator are zero or more expressions separated by commas — the actual arguments to the function.

The postfix-expression must be of one of these types:

• Function returning type T. An example declaration is

  T func( int i )
  

• Pointer to a function returning type T. An example declaration is

  T (*func)( int i )
  

• Reference to a function returning type T. An example declaration is

  T (&func)(int i)
  

• Pointer-to-member function dereference returning type T. Example function calls are

  (pObject->*pmf)();
  (Object.*pmf)();
