I have tried to create an application which would send a wireless signal from the iphone simulator to a windows computer running Windump, but my efforts have failed so far. It seems that some people on these forums are more knowledgeable of the TCP/IP coding of the mac, and I would like to know if there is anything wrong with my code, what I should do, and if there is anything critically wrong with it.

Any input would be welcome.



int fd = -1;
CFSocketRef socket;
socket = CFSocketCreate(kCFAllocatorDefault, PF_INET, SOCK_STREAM,
IPPROTO_TCP, 0, NULL, NULL);
if ( socket == NULL) {
NSLog(@"CfSocketCreate Failed");
}else{
if( socket ) {
fd = CFSocketGetNative(socket);
if (fd == -1) {

NSLog(@"CfSocketGetnative Failed");}
else{
int yes = 1;
setsockopt(fd, SOL_SOCKET, SO_REUSEADDR, (void *)&yes, sizeof(yes));

struct sockaddr_in addr;
memset(&addr, 0, sizeof(addr));
addr.sin_len = sizeof(addr);
addr.sin_family = AF_INET;
addr.sin_port = htons(9595); //port
inet_aton("192.168.2.3", &addr.sin_addr); //ip adress
NSData *address = [NSData dataWithBytes:&addr length:sizeof(addr)];
CFSocketError e = CFSocketSetAddress(socket, (CFDataRef)address);
if(e != kCFSocketSuccess ) {
NSLog(@"Could not bind to address");
}else{
char msg []= "helloworld";
CFDataRef Data = CFDataCreate(NULL, (const UInt8*)msg, sizeof(msg));
CFSocketSendData(socket,NULL, Data, 1000);}
}} else {
NSLog(@"No server socket");
}
}

By the way, the code is inside the ApplicationDidFinsihLaunching part of the code.
