Hello,
in the attachement there is a small program with a function 'getH' that
should return a histogram (as a real histogram, not as a pointer).
When starting the program (using ROOT Version 3.02/07 on g++-Linux) with
'prog()' two histograms 'h2' and 'h3' are created with the function
'getH'.
When trying to create 'h3' the value of 'counter' is 1, so that the adress
of 'h1' in 'getH' is printed out. Ths works but 'h1' is not defined yet!!
'h1' will be defined some lines later ('TH1F h1=...').
But why do ROOT know the existence of 'h1' before its creation?
Does ROOT not delete 'h1' at the end of 'getH' (as it is the standard
procedure for any C++ program)?
Is this a bug? Or is this extra property of ROOT?
Cheers
A. Dietz
