Problem regarding binding of Socket..

hi
my code is not being able to bind socket, neither my code is leaving anywhere.
i am giving my piece of code, if anybody can suggest that what could be possible reasons to this problem....

i want to make clear that i am running this code on emultor n i have issued Open(socketserversession,KAfInet,KSockDatagram,KUnspecified); prior to CSocket::Bind() without any RConnection instance.
N also iSocket is member variable of CSocket class.

TInt CSocket::Bind(TUint aLocalPort)
{
   TInetAddr anAddr(aLocalPort);
   const TUint32 KInetAddr = INET_ADDR(127,0,0,1);
   anAddr.SetAddress(KInetAddr);
   User::LeaveIfError(iSocket.Bind(anAddr));

   TInetAddr addr;

   iSocket.LocalName(addr);
             //At this point i am checking whether socket is binded to correct address or not.           

   if(! addr.Match(anAddr))
   {
             //control of the program is getting inside this if statement.
             }   

   iStateOfSocket=ESocketBinded;//Socket state changed.
   return 1;
}
