Re: cint problems/changes in head

Constantin,

Yes, today I decreased a parameter in CINT (G__MAXFUNCPARA) from 40 to 20. It turns out that accepting functions up to 40 parameters in the interactive interface
was penalizing everybody else designing good interfaces with less parameters.
The cost in memory was totally prohibitive giving the current structure of CINT with
some fixed length dimensions in the area describing functions arguments.

The solution to this problem is simple. Add the statement   #ifndef __CINT__

        void myfunction with more 20 arguments   #endif
in the section of your header files declaring the prototypes of such functions.
