+.SH DESCRIPTION
+.IX Header "DESCRIPTION"
+A class providing an object based interface to SysV IPC shared memory.
+.SH METHODS
+.IX Header "METHODS"
+.IP "new ( KEY , SIZE , FLAGS )" 4
+.IX Item "new ( KEY , SIZE , FLAGS )"
+Creates a new shared memory segment of \f(CW\*(C`SIZE\*(C'\fR bytes size associated
+with \f(CW\*(C`KEY\*(C'\fR. A new segment is created if
+.RS 4
+.IP \(bu 4
+\&\f(CW\*(C`KEY\*(C'\fR is equal to \f(CW\*(C`IPC_PRIVATE\*(C'\fR
+.IP \(bu 4
+\&\f(CW\*(C`KEY\*(C'\fR does not already have a shared memory segment associated
+with it, and \f(CW\*(C`\fR\f(CIFLAGS\fR\f(CW & IPC_CREAT\*(C'\fR is true.
+.RE
+.RS 4
+.Sp
+On creation of a new shared memory segment \f(CW\*(C`FLAGS\*(C'\fR is used to
+set the permissions.  Be careful not to set any flags that the
+Sys V IPC implementation does not allow: in some systems setting
+execute bits makes the operations fail.
+.RE
+.IP id 4
+.IX Item "id"
+Returns the shared memory identifier.
+.IP "read ( POS, SIZE )" 4
+.IX Item "read ( POS, SIZE )"
+Read \f(CW\*(C`SIZE\*(C'\fR bytes from the shared memory segment at \f(CW\*(C`POS\*(C'\fR. Returns
+the string read, or \f(CW\*(C`undef\*(C'\fR if there was an error. The return value
+becomes tainted. See shmread.
+.IP "write ( STRING, POS, SIZE )" 4
+.IX Item "write ( STRING, POS, SIZE )"
+Write \f(CW\*(C`SIZE\*(C'\fR bytes to the shared memory segment at \f(CW\*(C`POS\*(C'\fR. Returns
+true if successful, or false if there is an error. See shmwrite.
+.IP remove 4
+.IX Item "remove"
+Remove the shared memory segment from the system or mark it as
+removed as long as any processes are still attached to it.
+.IP is_removed 4
+.IX Item "is_removed"
+Returns true if the shared memory segment has been removed or
+marked for removal.
+.IP stat 4
+.IX Item "stat"
+Returns an object of type \f(CW\*(C`IPC::SharedMem::stat\*(C'\fR which is a sub-class
+of \f(CW\*(C`Class::Struct\*(C'\fR. It provides the following fields. For a description
+of these fields see you system documentation.

+.IP "attach ( [FLAG] )" 4
+.IX Item "attach ( [FLAG] )"
+Permanently attach to the shared memory segment. When a \f(CW\*(C`IPC::SharedMem\*(C'\fR
+object is attached, it will use memread and memwrite instead of
+shmread and shmwrite for accessing the shared memory segment.
+Returns true if successful, or false on error. See \fBshmat\fR\|(2).
+.IP detach 4
+.IX Item "detach"
+Detach from the shared memory segment that previously has been attached
+to. Returns true if successful, or false on error. See \fBshmdt\fR\|(2).
+.IP addr 4
+.IX Item "addr"
+Returns the address of the shared memory that has been attached to in a
+format suitable for use with \f(CWpack(\*(AqP\*(Aq)\fR. Returns \f(CW\*(C`undef\*(C'\fR if the shared
+memory has not been attached.
