Need information about data and bss segment address access in cygwin

Hi, I'm trying to understand how Cygwin implement fork in windows. When I browse through the fork code I found Cygwin copies the data segment,bss segment etc as rc = fork_copy (pi, "user/cygwin data", user_data->data_start, user_data->data_end, user_data->bss_start, user_data
