- * The sysv ipc id's (msgid, semid, shmid) are integers arranged such
- * that they no subsystem will generate the same id as some other
- * subsystem; nor do these ids overlap file descriptors (the other
- * common integer ids).  Since Cygwin can allocate more than OPEN_MAX
- * file descriptors, it can't be guaranteed not to overlap, but it
- * should help catch some errors.
- *
- * msgid's: OPEN_MAX,     OPEN_MAX + 3, OPEN_MAX + 6, . . .
- * semid's: OPEN_MAX + 1, OPEN_MAX + 4, OPEN_MAX + 7, . . .
- * shmid's: OPEN_MAX + 2, OPEN_MAX + 5, OPEN_MAX + 8, . . .
- *
- * To further ensure that ids are unique, if ipc objects are created
- * and destroyed and then re-created, they are given new ids by
- * munging the basic id (as above) with a sequence number.
- *
- * Internal ipc id's, which are 0, 1, ... within each subsystem (and
- * not munged with a sequence number), are used solely by the ipcs(8)
- * interface.
