C++ (Cpp) fill_entry_key Examples

Example #1

File: key.C Project: lostRating/database_project2

void make_entry(KeyDataEntry *target,
                AttrType key_type, const void *key,
                nodetype ndtype, Datatype data,
                int *pentry_len)
{
  int keylen, datalen;
  
  fill_entry_key(&target->key, key, key_type, &keylen);

  // below we can't say "&target->data" because <data> field may actually
  // start before that location (recall that KeyDataEntry is simply 
  // a chunk of memory big enough to hold any legal <key,data> pair).
  fill_entry_data((char *) (((char *)target) + keylen),
                  data, ndtype,  
                  &datalen);                
  *pentry_len = keylen + datalen;
