I am trying to use the apple document "Setting Up Socket Streams"
(
http://developer.apple.com/documentation/Cocoa/Conceptual/Streams/
Articles/NetworkStreams.html) to connect to a telnet server. I wrote
the following code and get no output. I am trying to print what was
returned in the buffer after the connection. I get no output except for
my first "hi"
Thanks.

int main(int argc, const char *argv[])
{
NSAutoreleasePool *pool = [[NSAutoreleasePool alloc] init];
NSLog(@"hi:");
NSHost *aHost = [NSHost hostWithName:@"fibs.com"];
NSInputStream *iStream = [[NSTask alloc] init];
NSOutputStream *oStream = [[NSTask alloc] init];
[NSStream getStreamsToHost:aHost port:4321 inputStream:&iStream
outputStream:&oStream];
[iStream retain];
[oStream retain];
[iStream setDelegate:iStream];
[oStream setDelegate:oStream];
[iStream scheduleInRunLoop:[NSRunLoop currentRunLoop]
forMode:NSDefaultRunLoopMode];
[oStream scheduleInRunLoop:[NSRunLoop currentRunLoop]
forMode:NSDefaultRunLoopMode];
[iStream open];
[oStream open];
NSMutableData *_data = [[NSMutableData alloc] init];
int bytesRead;
if(!_data) {
_data = [[NSMutableData data] retain];
}
uint8_t buf[1024];
unsigned int len = 0;
unsigned char secondBuffer[20];
len = [(NSInputStream *)iStream read:buf maxLength:1024];
if(len) {
[_data appendBytes:(const void *)buf length:len];
bytesRead = bytesRead +len;
} else {
NSLog(@"no buffer!");
}
[_data getBytes:secondBuffer];
NSLog(@"hi2:");
NSLog(@"hi2:", (char *)secondBuffer);
[pool release];
return NSApplicationMain(argc, argv);
}
