I was wondering if its possible or if there is an easy way of creating a copy of a bmap?

What I would like to do is something like:

Code:
BMAP* my_bmap;
BMAP* my_copy;

my_bmap = bmap_create("my_file.jpg");
my_copy = bmap_copy(my_bmap);


I know there is no bmap_copy() command, but the idea is to create a copy of a given bmap - so i would have 2 seperate bmaps that are the same image. Is that possible?
