Subject: [c-prog] [C++: passing a list to a function --mod] plz help
me.................................its urgent.............
[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.......
