Using the runtime API like this is a little like using `doLast()` and `doFirst()` to attach extra actions to a task, except in this case we’re attaching information about inputs and outputs.

//		Channel: 1,
//		Addr:    [6]byte{0x11, 0x22, 0x33, 0xaa, 0xbb, 0xcc}, // CC:BB:AA:33:22:11
//	})
//	Write(fd, []byte(`hello`))
type SockaddrRFCOMM struct {
	// Addr represents a bluetooth address, byte ordering is little-endian.
	Addr [6]uint8

	// Channel is a designated bluetooth channel, only 1-30 are available for use.
	// Since Linux 2.6.7 and further zero value is the first available channel.
	Channel uint8

	case *dwarf.TypedefType:
		// C has much more relaxed rules than Go for
		// implicit type conversions. When the parameter
		// is type T defined as *X, simulate a little of the
		// laxness of C by making the argument *X instead of T.
		if ptr, ok := base(dt.Type).(*dwarf.PtrType); ok {
			// Unless the typedef happens to point to void* since
