[Qt-interest] QSharedMemory::create takes an int... why?

I completely agree.

The API specifies "int". This data type is signed, so the API specifies a 
signed value for an interface in which negative quantities have no 
meaning. It would have been possible to defend "unsigned int", but plain 
"int" is broken.

The debate herein on the length of "int" is further demonstration of its 
poor suitability for this particular interface. It's also worrying to 
witness debate on the behaviour of fundamental C++ data types. The ISO 
standard should be the first and last word on this subject. If reading 
ISO/IEC 14882:2003, please see section 3.9.1.

The suggestion of a "size_t" is sensible. I hope the Qt engineers 
recognise the fault and adopt an appropriate solution. For further 
information, please see ISO/IEC 14882:2003 section 5.3.3. See also:
