The pointer is owned by the CStringA. Your example as written is undefined, because when the CStringA goes out of scope, it takes the pointer with it. ncharStr is an observer, not an owner. I tried to explain t
The returned C string is guaranteed to be valid only until either the receiver is freed, or until the current memory is emptied, whichever occurs first. You should copy the C string or usegetCString(_:maxLength:encoding:)if it needs to store the C string beyond this time. ...

If nullTerminatedCString is not a NULL-terminated C string, or encoding does not match the actual character encoding, the results are undefined. Special Considerations Only 8-bit encodings are supported, as encodings that have a greater width, such as UTF-16, may include a NULL byte in a si...
