The <TT>ipcrm</TT> command can be used to remove an IPC object from the kernel. While IPC
|
|
objects can be removed via system calls in user code (we'll see how in a moment), the need
|
|
often arises, especially under development environments, to remove IPC objects manually. Its
|
|
usage is simple:
|
|
<P>
|
|
<P>
|
|
<HR><PRE>ipcrm <msg | sem | shm> <IPC ID></PRE>
|
|
<HR>Simply specify whether the object to be deleted is a message queue (<EM>msg</EM>), a semaphore
|
|
set (<EM>sem</EM>), or a shared memory segment (<EM>shm</EM>). The IPC ID can be obtained by
|
|
the <TT>ipcs</TT> command. You have to specify the type of object, since identifiers are unique
|
|
among the same type (recall our discussion of this earlier).
