Packetize data to send it over tcp sockets
Hello All,
I am very new to socket programming and client server architecture. I have to write a client which will send some data to server and server will display it on its console. I am ready with both client and server but my problem is with packetizing of data --

I have structure which contains info to be sent to server. It looks like below --

Code:
typedef struct wordInfo
{
    int lineNo;
    int wordCnt;
    struct wordInfo *next;
}wordStats;

typedef struct Info
{
	char word[MAX_LENGTH];
        int totoalCount;
        wordStats pwHead[10];
}sharedInfo;

    sharedInfo shinfo[15];

My question is how can I send this info to server so that it will interpret this info as I wanted --

vde_over_ns

VDE_OVER_NS(1)						      General Commands Manual						    VDE_OVER_NS(1)

NAME

       vde_over_ns - Steganographic cable over NS protocol for Virtual Distributed Ethernet

SYNOPSIS

       vde_over_ns [-D] [-c server_address] [-s vde_plug] [-i ip.to.bi.nd] domain.name

DESCRIPTION

       A vde_over_ns allows to connect two remote vde_switches through steganographic NS query/response datagrams.  e.g.:

       dpipe vde_plug /tmp/s1 = vde_over_ns tun.mydomain.vde

       binds  to  udp port 53 and listen for incoming steganographic NS queries (server mode).	All the traffic to/from stdout/stdin is redirected
       to the client via ns responses.

       creates a wire between two vde_switches (with sockets /tmp/s1 and /tmp/s2 respectively). This cable looses  10%	of  the  packets  in  each
       direction.

       The same vde_over_dns server can be created using:

       vde_over_ns -s /tmp/s1 tun.mydomain.vde

       The  syntax is almost identical for the client mode, except that to have a vde_over_ns client connect to that server, the  -c server option
       must be specified.

OPTIONS

       -s vdeplug
	      If specified, the vde_over_ns will connect to the local vde socket vdeplug instead pf stdin/stdout, using the libvdeplug library.

       -D     Detach console and send the process to background.

       -b ip.to.bind
	      The NS server will bind only to the specified ip, instead of any ip.  Only valid in server mode (without -c)

       -c server_addr
	      If specified, client mode is enabled. Vde_over_ns will try to send NS requests to server_addr. If  not  specified,  server  mode	is
	      enabled by default.
