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.......

};
void col_sep2(IplImage * img){
IplImage * con_string=converting_to_connected_string(img,30);
int i,j,k,i1=0;
int step1 = img->widthStep/sizeof(uchar);
int count=0,flag=0,count1=0;
list<col_info> l;
for(j=0;j<con_string->width;j++)
{

cvSaveImage("D:/outdir/imkcon.jpg",con_string);

i am getting error like:
