reinterpret_cast< T > (arg)

Description 

In the statement, reinterpret_cast< T > (arg), T must be a pointer, reference, arithmetic type, pointer to function, or pointer to member. 

A pointer can be explicitly converted to an integral type. 

An integral arg can be converted to a pointer. Converting a pointer to an integral type and back to the same pointer type results in the original value. 

A yet undefined class can be used in a pointer or reference conversion. 

A pointer to a function can be explicitly converted to a pointer to an object type provided the object pointer type has enough bits to hold the function pointer. A pointer to an object type can be explicitly converted to a pointer to a function only if the function pointer type is large enough to hold the object pointer.
