CCS: CC3200 how to get port number from socket or packet?

Tool/software: Code Composer Studio

I have a CC3200 connecting via P2P to an Android phone with the Android as the Group Owner. The CC3200 sends a UDP packet on a prefixed port (8080) from which the Android retrieves its IP and dynamically generated port number. The Android stores that information and all future communication with the CC320 occurs over the dynamically generated port.

My problem is with finding the dynamically generated port on the CC3200. How do I extract it from the socket and save it to a variable?

My code is from the udp_socket example (slightly modified) as follows.

int UdpSendSocket(unsigned short usPort)
{
	SlSockAddrIn_t  sAddr;
	int             iCounter;
    int             iAddrSize;
    int             iSockID;
    int             iStatus;
    short           sBufLen;

    // filling the buffer
    for (iCounter=0 ; iCounter < strlen(g_cAck) ; iCounter++)
    {
    	g_cBsdBuf[iCounter] = (char)(g_cAck[iCounter]);
    }

    //sTestBufLen  = BUF_SIZE;  //original code
    //set buffer length to size of message
    sBufLen = strlen(g_cAck);

    //filling the UDP server socket address
    sAddr.sin_family = SL_AF_INET;
    sAddr.sin_port = sl_Htons((unsigned short)usPort);					//rearranges order of bytes for port
    sAddr.sin_addr.s_addr = sl_Htonl((unsigned int)g_ulGatewayIp);		//rearranges order of bytes for IP

    iAddrSize = sizeof(SlSockAddrIn_t);

    // creating a UDP socket
    iSockID = sl_Socket(SL_AF_INET,SL_SOCK_DGRAM, 0);
    if( iSockID < 0 )
    {
        // error
        ASSERT_ON_ERROR(SOCKET_CREATE_ERROR);
    }

    // for a UDP connection connect is not required
    		// sending packet
            iStatus = sl_SendTo(iSockID, g_cBsdBuf, sBufLen, 0,
                                    (SlSockAddr_t *)&sAddr, iAddrSize);
            if( iStatus <= 0 )
            {
                // error
                sl_Close(iSockID);
                ASSERT_ON_ERROR(SEND_ERROR);
            }

    UART_PRINT("Sent %u packets successfully\n\r", g_ulPacketCount);

    //closing the socket after sending 1 packet
    sl_Close(iSockID);

    return SUCCESS;
}
