Code:

---

 
typedef struct MYDATA {
  int x;
  char c[20];
} MYDATA;
 

MYDATA mydata;
 
// sending data
mydata.x = 1;
strcpy(mydata.c,"Test!");
send_data_to(NULL,mydata,sizeof(MYDATA));
 
//receiving data
function on_client_event(void* buffer) 
{
  if (event_type == EVENT_DATA)
    memcpy(mydata,buffer,sizeof(MYDATA));
}
