I don't know if this works, but maybe like this:

Code:

typedef struct MYDATA1 {
  int x;
  char c[20];
} MYDATA;
typedef struct MYDATA2 {
  int x;
  int y;
  char c[20];
} MYDATA2;
... 
MYDATA1* mydata1 = { x = 1; c = "Test!"; }
MYDAT21* mydata2 = { x = 1; y = 1; c = "Test!"; }
 
// sending data
send_data_to(NULL,mydata,sizeof(MYDATA1));
 
//receiving data
function on_client_event(void* buffer) 
{
  if (event_type == EVENT_DATA)
    if(sizeof(buffer)==sizeof(MYDATA1))
      ....
    if(sizeof(buffer)==sizeof(MYDATA2))
      ....
}

If you want to see if the struct has changed, just send an event after you updated the struct or you could save the content of the struct and check if the content has changed. Visit: http://www.anet-plugin.com for further informations. The Manual should give you an idea of how a struct can be sent (enet_send_data() is the function you are looking for).

Wouldn't this do?

Code:

Code:typedef struct MYDATA1 {
  bool dirty;
  int x;
  char c[20];
} MYDATA;
typedef struct MYDATA2 {
  bool dirty;
  int x;
  int y;
  char c[20];
} MYDATA2;
... 
MYDATA1* mydata1 = { dirty = 0,x = 1; c = "Test!"; }
MYDAT21* mydata2 = { dirty =0, x = 1; y = 1; c = "Test!"; }
 
// sending data
mydata1.dirty=1;
send_data_to(NULL,mydata,sizeof(MYDATA1));
 
//receiving data
function on_client_event(void* buffer) 
{
  if (event_type == EVENT_DATA)
    if(Mydata1.dirty == 1)
    {
       Do_Something_Dirty1();
       mydata1.dirty =0;
    }
      ....
       if(Mydata2.dirty == 1)
    {
       Do_Something_Dirty2();
       mydata2.dirty =0;
    }
...

}
