Right.

Alin, you can start by reading the node "Garbage Collection" in the
ELisp manual, and then proceed reading alloc.c, where you will see
many functions named mark_SOMETHING and then gc_sweep that does the
sweep stage.  If you want more background before reading the ELisp
manual, try googling "mark and sweep garbage collection".
