Question

#define SYNC_DATA_CB list<string> (*syncData)(void)

I want to have in my class a member (static or not is not matter) that will hold the reference to the function pointer.

I tried to declare like this, but didnt compiled:

SyncProcess{
  public:
   SyncProcess(SYNC_DATA_CB);
   static SYNC_DATA_CB sync_cb_;
}

I think what you might be looking for is a typedef instead.

typedef list<string>(*syncData)(void);

class SyncProcess{
  public:
   SyncProcess( syncData );
   static syncData sync_cb_;
};
