Yes, I agree.
I was not sure the TApplication interface I have used is the best one.
One has to distinguish some how whether the base class TApplication or
derived class is in use and I was reluctant to involve any RTTI (ROOT or
native)
at this point.
I did think about "bool" type. However I found this type is proved to be
too restrictive.
Very often we need more then 2 possible values to choose from.
Usually there are 3 at least. For example the return value can be treated
in future as
a number of bytes read: if it is >=0 and -1,-2 ... left to indicate
some errors or exeptions
Anyway at this point I have no solid evidence one needs more then 2
values to back
the "int" return type.
