IOCreateReceivePort(_:_:)
Creates and returns a mach port suitable for receiving IOKit messages of the specified type.
Declaration
func IOCreateReceivePort(_ msgType: UInt32, _ recvPort: UnsafeMutablePointer<mach_port_t>!) -> kern_return_tParameters
- msgType:
Type of message to be sent to this port (kOSNotificationMessageID or kOSAsyncCompleteMessageID)
- recvPort:
The created port is returned.
Return Value
A kern_return_t error code.
Discussion
In the future IOKit may use specialized messages and ports instead of the standard ports created by mach_port_allocate(). Use this function instead of mach_port_allocate() to ensure compatibility with future revisions of IOKit.
