Hi

Could someone please tell us to print a char when receiving data as a struct? Here is an example:

...
struct rcv{
  int x1;
  float x2;
  char *x3;
}; 
rcv data_rcv;
...
if (recv(socket, &data_rcv, sizeof(data_rcv), 0) < 0)
printf("recv() failed");
...

printf("x1 = %d\n", data_rcv.x1);
printf("x2 = %f\n", data_rcv.x2); 

printf("x3 = %s\n", data_rcv.x3); // it doesn't print anything, why? 
...

Thanks for your replies-
