memory allocation/deallocation

[michaelkrauklis]

I'm a little confused as to the memory management of MFC. eg:

//Say you make a pointer declaration as so
char *temp_str = "temp string";

//Then you wrap a CString around it
CString *temp_cstring = new CString( temp_str );

//Then what happens when you deallocate the CString?
delete temp_cstring;

Does it deallocate the memory for temp_str as well as temp_cstring or only the memory allocated to the CString? MYenigmaSELF

This is from the MSDN library under CString:

"the constructors copy the input data into new allocated storage"

which means that when you do this:
new CString( temp_str );

the constructor makes a copy of the string. You will have to destroy the original "char*" string yourself.

Great, thanks. I was trying to find info on the destructor, not constructor. I guess I was looking in the wrong spot. Thanks again. MYenigmaSELF
