Inherited methods

From class java.lang.Object

`Object`	`clone()` Creates and returns a copy of this object.
`boolean`	`equals(Object obj)` Indicates whether some other object is "equal to" this one.
`void`	`finalize()` Called by the garbage collector on an object when garbage collection determines that there are no more references to the object.
`final Class<?>`	`getClass()` Returns the runtime class of this `Object`.
`int`	`hashCode()` Returns a hash code value for the object.
`final void`	`notify()` Wakes up a single thread that is waiting on this object's monitor.
`final void`	`notifyAll()` Wakes up all threads that are waiting on this object's monitor.
`String`	`toString()` Returns a string representation of the object.
`final void`	`wait(long timeoutMillis, int nanos)` Causes the current thread to wait until it is awakened, typically by being notified or interrupted, or until a certain amount of real time has elapsed.
`final void`	`wait(long timeoutMillis)` Causes the current thread to wait until it is awakened, typically by being notified or interrupted, or until a certain amount of real time has elapsed.
`final void`	`wait()` Causes the current thread to wait until it is awakened, typically by being notified or interrupted.

Fields

msg_flags

public int msg_flags

Flags on received message.

msg_iov

public final ByteBuffer[] msg_iov

Scatter/gather array

msg_name

public SocketAddress msg_name

Optional address.

Sendmsg: Caller must populate to specify the target address for a datagram, or pass null to send to the destination of an already-connected socket. Recvmsg: Populated by the system to specify the source address.

Public constructors

public StructMsghdr (SocketAddress msg_name, 
                ByteBuffer[] msg_iov, 
                StructCmsghdr[] msg_control, 
                int msg_flags)

Constructs an instance with the given field values

Parameters
`msg_name`	`SocketAddress`: This value may be `null`.
`msg_iov`	`ByteBuffer`: This value cannot be `null`.
`msg_control`	`StructCmsghdr`: This value may be `null`.
`msg_flags`	`int`
