CFSocketCreateWithSocketSignature(_:_:_:_:_:)

Creates a CFSocket object using information from a CFSocketSignature structure.

Declaration

func CFSocketCreateWithSocketSignature(_ allocator: CFAllocator!, _ signature: UnsafePointer<CFSocketSignature>!, _ callBackTypes: CFOptionFlags, _ callout: CFSocketCallBack!, _ context: UnsafePointer<CFSocketContext>!) -> CFSocket!

Parameters

  • allocator:

    The allocator to use to allocate memory for the new object. Pass NULL or Kcfallocatordefault to use the current default allocator.

  • signature:

    A Cfsocketsignature identifying the communication protocol and address with which to create the CFSocket object.

  • callBackTypes:

    A bitwise-OR combination of the types of socket activity that should cause callout to be called. See Cfsocketcallbacktype for the possible activity values.

  • callout:

    The function to call when one of the activities indicated by callBackTypes occurs.

  • context:

    A structure holding contextual information for the CFSocket object. The function copies the information out of the structure, so the memory pointed to by context does not need to persist beyond the function call. Can be NULL.

Return Value

The new CFSocket object, or NULL if an error occurred. Ownership follows the The Create Rule.
