Function

Typical type information in a function name looks like this:

  • Optional: Prefix _ (means __based property is used)
  • Access level and function type
  • Conditional: __based property, if used
  • Conditional: adjustor property (as encoded unsigned number), if thunk function
  • Conditional: CV-class modifier of function, if non-static member function
  • Function property

The table below shows codes for access level and function type:

none static virtual thunk
private: A, B C, D E, F G, H
protected: I, J K, L M, N O, P
public: Q, R S, T U, V W, X
none Y, Z

This kind of thunk function is always virtual, and used to represent the logical this adjustor property, which means an offset to the true this value in some multiple inheritance situations.

Famous quotes containing the word function:

    The uses of travel are occasional, and short; but the best fruit it finds, when it finds it, is conversation; and this is a main function of life.
    Ralph Waldo Emerson (1803–1882)

    We are thus able to distinguish thinking as the function which is to a large extent linguistic.
    Benjamin Lee Whorf (1897–1934)

    My function in life is not to be a politician in Parliament: it is to get something done.
