Member operator to overload memory deallocation process part provided by
Operator Delete Statement when applying to a UDT (User Defined Type).
Syntax
Parameters
buf
A pointer to memory that has been allocated by
New Overload operator or
New[] Overload operator, the array-version of
New Overload operator.
Description
The member operator
Delete Overload overloads the memory deallocation process part provided by the
Delete Statement operator when applying to a UDT (User Defined Type). So the user can define its own memory deallocation process part.
But before that, the UDT instance destruction process part provided by the
Delete Statement operator is not modified.
Delete[] Overload operator is the array-version of
Delete Overload operator and overloads the memory deallocation process provided by the
Delete[] Statement operator when applying to a UDT (User Defined Type).
Memory freed with
Delete Overload operator must have be allocated by also defining a
New Overload operator. Memory freed with
Delete[] Overload operator must have been allocated by also defining a
New[] Overload operator, the array-version of
New Overload operator. You cannot mix and match the different versions of the operators.
Member operators
Delete Overload, and
Delete[] Overload are always static, even if not explicitly declared (
Static keyword is unnecessary but allowed). Thus, they do not have an implicit
This instance argument passed to them (because instance already been destroyed).
