Hello,
i'm trying to use shmat specifying an address but each time i got the
error: invalid argument.
in fact i need to map something just next to something previously mapped
without argument.
is this a limitation of cygserver ?
thanks

In fact i wasn't using the SHM_RNd flag.
In details here is what i do:
- get a shared segment of with size= SIZE (SIZE multiple of SHMLBA)
- attach the segment without specifying address and storing the result
in beginaddress
- attach the segment

Ok i perhaps find a solution or a beginning of solution:
