CFStreamCreatePairWithSocketToCFHost(_:_:_:_:_:)

Creates readable and writable streams connected to a given CFHost object.

Declaration

func CFStreamCreatePairWithSocketToCFHost(_ alloc: CFAllocator?, _ host: CFHost, _ port: Int32, _ readStream: UnsafeMutablePointer<Unmanaged<CFReadStream>?>?, _ writeStream: UnsafeMutablePointer<Unmanaged<CFWriteStream>?>?)

Parameters

  • alloc:

    The allocator to use to allocate memory for the CFReadStream and CFWriteStream objects. Pass NULL or kCFAllocatorDefault to use the current default allocator.

  • host:

    A CFHost object to which the streams are connected. If unresolved, the host will be resolved prior to connecting.

  • port:

    The TCP port number to which the socket streams should connect.

  • readStream:

    Upon return, contains a CFReadStream object connected to the host host on port port, or NULL if there is a failure during creation. If you pass NULL, the function will not create a readable stream. Ownership follows the 20001148 103029.

  • writeStream:

    Upon return, contains a CFWriteStream object connected to the host host on port port, or NULL if there is a failure during creation. If you pass NULL, the function will not create a writable stream. Ownership follows the 20001148 103029.

Discussion

The streams do not create a socket or connect to the specified host until you open one of the streams.

Most properties are shared by both streams. Setting a shared property for one stream automatically sets the property for the other.
