Thanks for reply.
When I run client/server,client get connected with server but when I
send some data to client it does not receive by the client. I mean to
say callback function "receiveData" is not called by CFSocket. This
problem is occur when I create the CFSocket on a thread as I have
given the source code below. But when I create the CFSocket in a
normal function it works properly.
My Sourcecode for CFSocket is as follows:
int main()
{
pthread_create( &tcpThread ,NULL ,TCPCFSocketCreate,NULL );
}
void* TCPCFSocketCreate(void* val)
{
char tcperrorMsg[MAX_SIZE ];
struct hostent *phostent;
socklen_t length;
CFSocketRef CFSocketchild ;
tcpPortNo =1024;
unsigned int ip = server.sin_addr.s_addr;
char *p=(char *)&ip;
bzero(&ipstr,15);
sprintf((char *)ipstr,"%d.%d.%d.%d",(unsigned char)p[0],(unsigned
char)p[1],(unsigned char)p[2],(unsigned char)p[3]);
struct sockaddr_in tcpip_sa;
iConnectTCPSocket=socket(AF_INET,SOCK_STREAM,0);
tcpip_sa.sin_len = sizeof(struct sockaddr_in);
tcpip_sa.sin_family = AF_INET;
tcpip_sa.sin_addr.s_addr = htonl(INADDR_ANY);
tcpip_sa.sin_port = htons(tcpPortNo);
phostent = gethostbyname(ipstr);
bcopy((char *)phostent->h_addr,
(char *)&tcpip_sa.sin_addr.s_addr,
phostent->h_length);
tcpip_sa.sin_len = sizeof(struct sockaddr_in);
length = sizeof(struct sockaddr_in);
memset (&(tcpip_sa.sin_zero), '\0', 8);
if (connect(iConnectTCPSocket,(struct sockaddr
*)&tcpip_sa,sizeof(tcpip_sa)) < 0)
{
printf("Error: Connecting to Server.\n");
}
CFSocketchild=CFSocketCreateWithNative(NULL,(CFSocketNativeHandle)iConnectTCPSocket,kCFSocketDataCallBack,receiveData,NULL);
int isocketWRet = write(iConnectTCPSocket, &clientinfo, sizeof(clientinfo));
if(isocketWRet==0)
{
sprintf(tcperrorMsg ,strerror(errno));
}
CFRunLoopSourceRef childSource = CFSocketCreateRunLoopSource(NULL,
CFSocketchild, 0);
CFRunLoopRef loop = CFRunLoopGetCurrent();
CFRunLoopAddSource(loop, childSource, kCFRunLoopDefaultMode);
//CFRelease(childSource);
}
void receiveData(CFSocketRef child, CFSocketCallBackType type,
CFDataRef address, const void *data, void *info)
{
printf("Data from server\n");
}
Thanks,
Sunil.
