Fifos persist on reboot on Linux or Cygwin. They live on the
filesystem. I don't see how POSIX IPC shared memory and semaphores
Sorry, I meant unix/bsd sockets.
Regarding the POSIX IPC's, they are stored in /dev . In regular *nix,
/dev do not represent "physical" files on the filesystem, hence they do
not persist over boot.
In cygwin, they actually do represent physical files. So if they are not
freed correctly by the program, the persist over to the next boot.
