In some cases (e.g. X Windows/Fresco) there are C++ interfaces that have evolved from pre-existing C interfaces. But I suspect the great majority of interfaces used by C++ programmers are 'reused' C interfaces. dave -- --The preceeding opinions do not necessarily reflect the opinions of --The MITRE Corporation or its sponsors. -- "A good plan violently executed -NOW- is better than a perfect plan -- next week" George Patton -- "Any damn fool can write a plan.
