Descriptors FAQ

I want to initialise a TPtr later, but declare it now. How do I do this?

TPtr8 myPtr(NULL, 0);

or, for member data, in the constructor's initialization list:

CMyClass::CMyClass()
: iPtr(NULL, 0)
{}

To assign to it later, use Set() as described in 16. What does TPtrC::Set() do?. For example:

myTPtr.Set(myHBufC->Des());
iPtr.Set(someExistingBuf);
