The binary operator .* combines its first operand, which must be an object of class type, with its second operand, which must be a pointer-to-member type.

The binary operator ->* combines its first operand, which must be a pointer to an object of class type, with its second operand, which must be a pointer-to-member type.

In an expression containing the .* operator, the first operand must be of the class type of the pointer to member specified in the second operand or of a type unambiguously derived from that class.

In an expression containing the ->* operator, the first operand must be of the type "pointer to the class type" of the type specified in the second operand, or it must be of a type unambiguously derived from that class.

Example

The following example calls the member function designated by pMemberFunc for the object pointed to by pObject and passes the parameter of 6:

// Example of the pointer to member operators
(pObject->*pMemberFunc) (6);
