CFStreamCreatePairWithSocketToNetService(_:_:_:_:)

Creates a pair of streams for a CFNetService.

Declaration

func CFStreamCreatePairWithSocketToNetService(_ alloc: CFAllocator?, _ service: CFNetService, _ 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.

  • service:

    Reference to the CFNetService to which the streams are to be connected. If the service is not resolved, the service will be resolved before the streams are connected.

  • writeStream:

    Upon return, contains a CFWriteStream object connected to the service specified by service, 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, resolve the service, or connect to the service’s 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.

Special Considerations

This function is thread safe.
