how to send files

[munna_dude]

hi all
this is wellknown question about file sending.

#include <gtk/gtk.h>
#include <netdb.h>
#include <stdio.h>
#include <stdlib.h>
#include <linux/sockios.h>
#include <string.h>
#include <math.h>
#include <dirent.h>

#include <sys/types.h>
#include <sys/stat.h>
#include <fcntl.h>
#include <errno.h>
#include <unistd.h>
#include <syslog.h>

these for global declarations

GtkWidget *dialog;
GtkWidget *parent_window;
gint result;
gchar *file;
gchar *ind;
gchar *post=NULL;
void server1();
void server2();
int n,i=2010,j=2030;
gchar *item=NULL,*item2=NULL,*item1=NULL, *text=NULL;
gchar *text1=NULL,*post1=NULL;

when we pressed okbutton,singal will comes in to this

static void file_ok_sel()
{
        g_print ("%s\n",file );

	item1= g_strconcat  (file,NULL);
	post=g_strconcat  (file,NULL);

  /*  pthread_t thread1;
    int  iret1;
    iret1=pthread_create( &thread1, NULL, server2, NULL);
    //pthread_join( thread1, 0);
    pthread_detach( thread1);*/
	server2();

}

main function
here i declared the gtk window and signal of okbutton

int main( int   argc,
          char *argv[] )
{
    
    gtk_init (&argc, &argv);
    
dialog = gtk_file_chooser_dialog_new ("File Selection", NULL, GTK_FILE_CHOOSER_ACTION_OPEN, GTK_STOCK_CANCEL, GTK_RESPONSE_CANCEL, GTK_STOCK_OPEN, GTK_RESPONSE_OK, NULL);


result = gtk_dialog_run (GTK_DIALOG (dialog));

switch (result)
{
case (GTK_RESPONSE_OK):

 file = gtk_file_chooser_get_filename (GTK_FILE_CHOOSER (dialog));
 g_print("file=%s\n",file);
file_ok_sel();
  /* Use the filename here. */
default:
  gtk_widget_destroy (dialog);
}

    gtk_main ();
    return 0;
}

and here i declared sever and client connections

void error(char *msg)
{
    perror(msg);
    exit(0);
}

void server2()
{
    int sockfd, portno, n;
    struct sockaddr_in serv_addr;
    struct hostent *server;
  // int i=2030;
    char buffer[256];
  portno = i;
printf("i=%d\n",i);
    sockfd = socket(AF_INET, SOCK_STREAM, 0);
    if (sockfd < 0) 
        error("ERROR opening socket");
    server = gethostbyname("192.168.xxx.xxx");
    if (server == NULL) {
        fprintf(stderr,"ERROR, no such host\n");
        exit(0);
    }


    bzero((char *) &serv_addr, sizeof(serv_addr));
    serv_addr.sin_family = AF_INET;
    bcopy((char *)server->h_addr, 
         (char *)&serv_addr.sin_addr.s_addr,
         server->h_length);

    serv_addr.sin_port = htons(portno);
    if (connect(sockfd,&serv_addr,sizeof(serv_addr)) < 0) 
{

}

else
{
  post=g_strconcat(post,NULL);  
     g_print ("post=%s\n",post );  
   n = write(sockfd,post,strlen(post));
    if (n < 0) 
         error("ERROR writing to socket");
   
g_print("post======%s \n",post);

}
i++;
 server1();
   
}
void server1()
{
int sockfd, newsockfd, portno, clilen;
     char buffer[256],*item;
     struct sockaddr_in serv_addr, cli_addr;
         sockfd = socket(AF_INET, SOCK_STREAM, 0);
     if (sockfd < 0) 
        error("ERROR opening socket");
     bzero((char *) &serv_addr, sizeof(serv_addr));
     portno =j;
printf("j=%d\n",j);
bzero(item1,strlen(item1));
     serv_addr.sin_family = AF_INET;
     serv_addr.sin_addr.s_addr = INADDR_ANY;
     serv_addr.sin_port = htons(portno);
     if (bind(sockfd, (struct sockaddr *) &serv_addr,
              sizeof(serv_addr)) < 0) 
              error("ERROR on binding");
     listen(sockfd,5);
     clilen = sizeof(cli_addr);
     newsockfd = accept(sockfd, 
                 (struct sockaddr *) &cli_addr, 
                 &clilen);
printf("j=%d\n",j);
j++;
     if (newsockfd < 0) 
          error("ERROR on accept");
     
     n = read(newsockfd,item1,1024);
     if (n < 0) error("ERROR reading from socket");
     printf("Here is the message: %s\n",item1);
   
     if (n < 0) error("ERROR writing to socket");
item1[strlen(item1)]='\0';

int m;

g_print("%s \n",item1);

}

to compile the code

gcc fileselect.c -o fileselect `pkg-config gtk+-2.0 --cflags --libs'

it is is successfully compiled.
but it is unable to send a file to others.

help me

thank you in advance
