There is no code to update them. As the other rep
Thanks Cliff/Dave. I could not find the code where the dll data/bss
segments address are updated in cygwin. But in the fork code we are
doing a copy for all linked and loaded dlls data/bss segments by
giving the address as
for (dll *d = dlls.istart (DLL_LINK); d; d = dlls.inext ())

The linker places these variables
Thanks Dave your reply answered the question where they declared. But
how does these variables get the segment address of data and bss for a
running process to make a copy to the child process? This is the
questions which is a puzzle to me.
Thanks in Advance for your answer

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
