+=head1 DESCRIPTION
+
+A class providing an object based interface to SysV IPC message queues.
+
+=head1 METHODS
+
+=over 4
+
+=item new ( KEY , FLAGS )
+
+Creates a new message queue associated with C<KEY>. A new queue is
+created if
+
+=over 4
+
+=item *
+
+C<KEY> is equal to C<IPC_PRIVATE>
+
+=item *
+
+C<KEY> does not already have a message queue associated with
+it, and C<I<FLAGS> & IPC_CREAT> is true.
+
+=back
+
+On creation of a new message queue C<FLAGS> 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.
+
+=item id
+
+Returns the system message queue identifier.
+
+=item rcv ( BUF, LEN [, TYPE [, FLAGS ]] )
+
+Read a message from the queue. Returns the type of the message read.
+See L<msgrcv(2)>.  The BUF becomes tainted.
+
+=item remove
+
+Remove and destroy the message queue from the system.
+
+=item set ( STAT )
+
+=item set ( NAME => VALUE [, NAME => VALUE ...] )
+
+C<set> will set the following values of the C<stat> structure associated
+with the message queue.
+
+    uid
+    gid
+    mode (oly the permission bits)
+    qbytes
+
+C<set> accepts either a stat object, as returned by the C<stat> method,
+or a list of I<name>-I<value> pairs.
+
+=item snd ( TYPE, MSG [, FLAGS ] )
+
+Place a message on the queue with the data from C<MSG> and with type C<TYPE>.
+See L<msgsnd(2)>.
+
+=item stat
+
+Returns an object of type C<IPC::Msg::stat> which is a sub-class of
+C<Class::Struct>. It provides the following fields. For a description
+of these fields see you system documentation.
+
+    uid
+    gid
+    cuid
+    cgid
+    mode
+    qnum
+    qbytes
+    lspid

+=head1 DESCRIPTION
+
+A class providing an object based interface to SysV IPC semaphores.
+
+=head1 METHODS
+
+=over 4
+
+=item new ( KEY , NSEMS , FLAGS )
+
+Create a new semaphore set associated with C<KEY>. C<NSEMS> is the number
+of semaphores in the set. A new set is created if
+
+=over 4
+
+=item *
+
+C<KEY> is equal to C<IPC_PRIVATE>
+
+=item *
+
+C<KEY> does not already have a semaphore identifier
+associated with it, and C<I<FLAGS> & IPC_CREAT> is true.
+

+
+On creation of a new semaphore set C<FLAGS> 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.
+
+=item getall
+
+Returns the values of the semaphore set as an array.
+
+=item getncnt ( SEM )
+
+Returns the number of processes waiting for the semaphore C<SEM> to
+become greater than its current value
+
+=item getpid ( SEM )
+
+Returns the process id of the last process that performed an operation
+on the semaphore C<SEM>.
+
+=item getval ( SEM )
+
+Returns the current value of the semaphore C<SEM>.
+
+=item getzcnt ( SEM )
+
+Returns the number of processes waiting for the semaphore C<SEM> to
+become zero.
+
+=item id
+
+Returns the system identifier for the semaphore set.
+
+=item op ( OPLIST )
+
+C<OPLIST> is a list of operations to pass to C<semop>. C<OPLIST> is
+a concatenation of smaller lists, each which has three values. The
+first is the semaphore number, the second is the operation and the last
+is a flags value. See L<semop(2)> for more details. For example
+
+    $sem->op(
+	0, -1, IPC_NOWAIT,
+	1,  1, IPC_NOWAIT
+    );
+
+=item remove
+
+Remove and destroy the semaphore set from the system.
+
+=item set ( STAT )
+
+=item set ( NAME => VALUE [, NAME => VALUE ...] )
+
+C<set> will set the following values of the C<stat> structure associated
+with the semaphore set.
+
+    uid
+    gid
+    mode (only the permission bits)
+
+C<set> accepts either a stat object, as returned by the C<stat> method,
+or a list of I<name>-I<value> pairs.
+
+=item setall ( VALUES )
+
+Sets all values in the semaphore set to those given on the C<VALUES> list.
+C<VALUES> must contain the correct number of values.
+
+=item setval ( N , VALUE )
+
+Set the C<N>th value in the semaphore set to C<VALUE>
+
+=item stat
+
+Returns an object of type C<IPC::Semaphore::stat> which is a sub-class of
+C<Class::Struct>. It provides the following fields. For a description
+of these fields see your system documentation.

+=head1 DESCRIPTION
+
+A class providing an object based interface to SysV IPC shared memory.
+
+=head1 METHODS
+
+=over 4
+
+=item new ( KEY , SIZE , FLAGS )
+
+Creates a new shared memory segment of C<SIZE> bytes size associated
+with C<KEY>. A new segment is created if
+
+=over 4
+
+=item *
+
+C<KEY> is equal to C<IPC_PRIVATE>
+
+=item *
+
+C<KEY> does not already have a shared memory segment associated

+

+
+On creation of a new shared memory segment C<FLAGS> 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.
+
+=item id
+
+Returns the shared memory identifier.
+
+=item read ( POS, SIZE )
+
+Read C<SIZE> bytes from the shared memory segment at C<POS>. Returns
+the string read, or C<undef> if there was an error. The return value
+becomes tainted. See L<shmread>.
+
+=item write ( STRING, POS, SIZE )
+
+Write C<SIZE> bytes to the shared memory segment at C<POS>. Returns
+true if successful, or false if there is an error. See L<shmwrite>.
+
+=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.
+
+=item is_removed
+
+Returns true if the shared memory segment has been removed or
+marked for removal.
+
+=item stat
+
+Returns an object of type C<IPC::SharedMem::stat> which is a sub-class
+of C<Class::Struct>. It provides the following fields. For a description
+of these fields see you system documentation.
+
+    uid
+    gid
+    cuid
+    cgid
+    mode
+    segsz
+    lpid
+    cpid
+    nattch
+    atime
+    dtime
+    ctime
+
+=item attach ( [FLAG] )
+
+Permanently attach to the shared memory segment. When a C<IPC::SharedMem>
+object is attached, it will use L<memread> and L<memwrite> instead of
+L<shmread> and L<shmwrite> for accessing the shared memory segment.
+Returns true if successful, or false on error. See L<shmat(2)>.
+
+=item detach
+
+Detach from the shared memory segment that previously has been attached
+to. Returns true if successful, or false on error. See L<shmdt(2)>.
+
+=item addr
+
+Returns the address of the shared memory that has been attached to in a
+format suitable for use with C<pack('P')>. Returns C<undef> if the shared
+memory has not been attached.

+=head1 NAME
+
+IPC::SysV - System V IPC constants and system calls
+
+=head1 SYNOPSIS
+
+  use IPC::SysV qw(IPC_STAT IPC_PRIVATE);
+
+=head1 DESCRIPTION
+
+C<IPC::SysV> defines and conditionally exports all the constants
+defined in your system include files which are needed by the SysV
+IPC calls.  Common ones include
+
+  IPC_CREAT IPC_EXCL IPC_NOWAIT IPC_PRIVATE IPC_RMID IPC_SET IPC_STAT
+  GETVAL SETVAL GETPID GETNCNT GETZCNT GETALL SETALL
+  SEM_A SEM_R SEM_UNDO
+  SHM_RDONLY SHM_RND SHMLBA
+
+and auxiliary ones
+
+  S_IRUSR S_IWUSR S_IRWXU
+  S_IRGRP S_IWGRP S_IRWXG
+  S_IROTH S_IWOTH S_IRWXO
+
+but your system might have more.
+
+=over 4
+
+=item ftok( PATH )
+
+=item ftok( PATH, ID )
+
+Return a key based on PATH and ID, which can be used as a key for
+C<msgget>, C<semget> and C<shmget>. See L<ftok(3)>.
+
+If ID is omitted, it defaults to C<1>. If a single character is
+given for ID, the numeric value of that character is used.
+
+=item shmat( ID, ADDR, FLAG )
+
+Attach the shared memory segment identified by ID to the address
+space of the calling process. See L<shmat(2)>.
+
+ADDR should be C<undef> unless you really know what you're doing.
+
+=item shmdt( ADDR )
+
+Detach the shared memory segment located at the address specified
+by ADDR from the address space of the calling process. See L<shmdt(2)>.
+
+=item memread( ADDR, VAR, POS, SIZE )
+
+Reads SIZE bytes from a memory segment at ADDR starting at position POS.
+VAR must be a variable that will hold the data read. Returns true if
+successful, or false if there is an error. memread() taints the variable.
+
+=item memwrite( ADDR, STRING, POS, SIZE )
+
+Writes SIZE bytes from STRING to a memory segment at ADDR starting at
+position POS. If STRING is too long, only SIZE bytes are used; if STRING
+is too short, nulls are written to fill out SIZE bytes. Returns true if
+successful, or false if there is an error.
