localPort (property)

The TCP port in the local host where IPPort binds.

Syntax

@property (nonatomic,readwrite,assign,getter=localPort,setter=setLocalPort:) int localPort;
- (int)localPort;
- (void)setLocalPort:(int)newLocalPort;
public var localPort: Int32 {
  get {...}
set {...} }

Default Value

0

Remarks

The LocalPort property must be set before a connection is attempted. It instructs the class to bind to a specific port (or communication endpoint) in the local machine.

Setting it to 0 (default) enables the TCP/IP stack to choose a port at random. The chosen port will be shown by the LocalPort property after the connection is established.

LocalPort cannot be changed once a connection is made. Any attempt to set the LocalPort property when a connection is active will generate an error.

The LocalPort property is useful when trying to connect to services that require a trusted port in the client side.
