Hi folks, I've been writing a Cygwin application that uses a DLL that maps memory at the same virtual address as the default cygwin_shared address (0x0A000000). My DLL maps the memory before Cygwin's dll_entry point is called. I notice that open_shared correctly maps Cygwin's shared memory area at a different virtual address to the default. However, tty file handlers take a pointer (tc in class fhandler_termios) to the tty list held in this shared memory area. During a fork, this pointer is copied and never fixed up to account for differing cygwin_shared addresses between parent and child. My question is, is it a goal of Cywgin to avoid copying pointers to the shared memory areas during a fork?
