Initializer

init(machPort:options:)

Initializes a newly allocated NSMachPort object with a given Mach port and the specified options.

Declaration

init(machPort: UInt32, options f: NSMachPort.Options = [])

Parameters

machPort

The Mach port for the new port. This parameter should originally be of type mach_port_t.

options

Specifies options for what to do with the underlying port rights when the NSMachPort object is invalidated or destroyed. For a list of constants, see Mach Port Rights.

Return Value

Returns an initialized NSMachPort object that uses machPort to send or receive messages. The returned object might be different than the original receiver

Discussion

Depending on the access rights for machPort, the new port may be able to only send messages. If a port with machPort already exists, this method deallocates the receiver, then retains and returns the existing port.
