+.SH DESCRIPTION
+.IX Header "DESCRIPTION"
+A class providing an object based interface to SysV IPC semaphores.
+.SH METHODS
+.IX Header "METHODS"
+.IP "new ( KEY , NSEMS , FLAGS )" 4
+.IX Item "new ( KEY , NSEMS , FLAGS )"
+Create a new semaphore set associated with \f(CW\*(C`KEY\*(C'\fR. \f(CW\*(C`NSEMS\*(C'\fR is the number
+of semaphores in the set. A new set 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 semaphore identifier
+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 semaphore set \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 getall 4
+.IX Item "getall"
+Returns the values of the semaphore set as an array.
+.IP "getncnt ( SEM )" 4
+.IX Item "getncnt ( SEM )"
+Returns the number of processes waiting for the semaphore \f(CW\*(C`SEM\*(C'\fR to
+become greater than its current value
+.IP "getpid ( SEM )" 4
+.IX Item "getpid ( SEM )"
+Returns the process id of the last process that performed an operation
+on the semaphore \f(CW\*(C`SEM\*(C'\fR.
+.IP "getval ( SEM )" 4
+.IX Item "getval ( SEM )"
+Returns the current value of the semaphore \f(CW\*(C`SEM\*(C'\fR.
+.IP "getzcnt ( SEM )" 4
+.IX Item "getzcnt ( SEM )"
+Returns the number of processes waiting for the semaphore \f(CW\*(C`SEM\*(C'\fR to
+become zero.
+.IP id 4
+.IX Item "id"
+Returns the system identifier for the semaphore set.
+.IP "op ( OPLIST )" 4
+.IX Item "op ( OPLIST )"
+\&\f(CW\*(C`OPLIST\*(C'\fR is a list of operations to pass to \f(CW\*(C`semop\*(C'\fR. \f(CW\*(C`OPLIST\*(C'\fR 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 \fBsemop\fR\|(2) for more details. For example
+.Sp
+.Vb 4
+\&    $sem\->op(
+\&        0, \-1, IPC_NOWAIT,
+\&        1,  1, IPC_NOWAIT
+\&    );
+.Ve
+.IP remove 4
+.IX Item "remove"
+Remove and destroy the semaphore set from the system.
+.IP "set ( STAT )" 4
+.IX Item "set ( STAT )"
+.PD 0
+.IP "set ( NAME => VALUE [, NAME => VALUE ...] )" 4
+.IX Item "set ( NAME => VALUE [, NAME => VALUE ...] )"
+.PD
+\&\f(CW\*(C`set\*(C'\fR will set the following values of the \f(CW\*(C`stat\*(C'\fR structure associated
+with the semaphore set.

+.Vb 3
+\&    uid
+\&    gid
+\&    mode (only the permission bits)
+.Ve
+.Sp
+\&\f(CW\*(C`set\*(C'\fR accepts either a stat object, as returned by the \f(CW\*(C`stat\*(C'\fR method,
+or a list of \fIname\fR\-\fIvalue\fR pairs.
+.IP "setall ( VALUES )" 4
+.IX Item "setall ( VALUES )"
+Sets all values in the semaphore set to those given on the \f(CW\*(C`VALUES\*(C'\fR list.
+\&\f(CW\*(C`VALUES\*(C'\fR must contain the correct number of values.
+.IP "setval ( N , VALUE )" 4
+.IX Item "setval ( N , VALUE )"
+Set the \f(CW\*(C`N\*(C'\fRth value in the semaphore set to \f(CW\*(C`VALUE\*(C'\fR
+.IP stat 4
+.IX Item "stat"
+Returns an object of type \f(CW\*(C`IPC::Semaphore::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 your system documentation.
