Named Pipes using mkfifo and Cocoa

Question

I have a C++ application that uses named pipes by calling mkfifo and I would like to use them to connect to a Cocoa app. I have taken a look at NSPipe but there isn't an option to connect to a named pipe. Does anyone know how to connect NSPipes or something else I can tie into the NSNotificationCenter that can talk to named pipes?
Thank you for your time,
Tom

-(void)SomeFunc
const char * path = "/tmp/tom21";
if(mkfifo(path, 0666) == -1 && errno !=EEXIST){
NSLog(@"Unable to open the named pipe %c", path);
NSFileHandle * filehandleForReading;
int fd = open(path, O_RDWR | O_NDELAY);
filehandleForReading = [[NSFileHandle alloc] initWithFileDescriptor:fd closeOnDealloc: YES];
NSNotificationCenter *nc;
nc = [NSNotificationCenter defaultCenter];
[nc removeObserver:self];
[nc addObserver:self
selector:@selector(dataReady:)
name:NSFileHandleReadCompletionNotification
object:filehandleForReading];
[filehandleForReading readInBackgroundAndNotify];
And then here is the func that gets called by the Notification server
- (void)dataReady:(NSNotification *)n
NSData *d;
d = [[n userInfo] valueForKey:NSFileHandleNotificationDataItem];
NSLog(@"dataReady:%d bytes", [d length]);
if ([d length]) {
[self appendData:d];
//Tell the fileHandler to asychronusly report back
[filehandleForReading readInBackgroundAndNotify];
}
