CAutoPtr::Attach
Call this method to take ownership of an existing pointer.
Syntax
void Attach(
T* p
) throw( );
Parameters
- p
The CAutoPtr object will take ownership of this pointer.
Remarks
When a CAutoPtr object takes ownership of a pointer, it will automatically delete the pointer and any allocated data when it goes out of scope. If CAutoPtr::Detach is called, the programmer is again given responsibility for freeing any allocated resources.
In debug builds, an assertion failure will occur if the CAutoPtr::m_p data member currently points to an existing value; that is, it is not equal to NULL.
Example
See the example in the CAutoPtr Overview.
