31 .Nd "remove the specified message queues, semaphore sets, and shared segments"
46 utility removes the specified message queues, semaphores and shared memory
48 These System V IPC objects can be specified by their
49 creation ID or any associated key.
51 The following options are generic:
52 .Bl -tag -width indent
54 If specified once with -W or with -1 for an object, it will show
56 If specified twice with -W or with -1 for an objects, it will show
57 all removed objects and all failed removals.
59 Try to wipe all specified message queues, semaphores and shared
64 interface instead of the
66 interface to extract the required information.
69 is to operate on the running system,
72 will require read privileges to
76 The following options are used to specify which IPC objects will be removed.
77 Any number and combination of these options can be used:
78 .Bl -tag -width indent
80 Remove the message queue associated with the ID
84 Mark the shared memory segment associated with ID
87 This marked segment will be destroyed after the last detach.
89 Remove the semaphore set associated with ID
93 Remove the message queue associated with key
97 Mark the shared memory segment associated with key
100 This marked segment will be destroyed after the last detach.
102 Remove the semaphore set associated with key
107 The identifiers and keys associated with these System V IPC objects can be
110 If the identifier or the key is -1, it will remove all these objects.
