i ve already sent the total code...................
look
i have class like:
class Class
{
}
void func(){
std::list<Class> l;
l.push_back(Class(0));
l.push_back(Class(0));
func(&l);
}
i want to pass that list to different function but iits not working.............
like
void func2(list<Class> &l){
list<class>::iterator p=l.begin();
the element of the Class can not be accessed............................plz help
}//is not working..................

[Moderator- The subject line should reflect the nature of the

i am using C++ on msvc++ 2008 sp1......... .now my question is how can i pass
the stndrd template list to a different function void block_separation(
IplImage *,IplImage *,list<col_info> &)?????????? ????????? ????????? ?????i am
giving both function definition here.......
