Function HashTableUnlink

src/util/dict.c:538–540

Remove an element from the table, but without actually releasing * the key, value and dictionary entry. The dictionary entry is returned * if the element was found (and unlinked from the table), and the user * should later call `HashTableFreeUnlinkedEntry()` with it in order to release it. * Otherwise if the key is not found, NULL is returned. * * This function is useful when we want to remo

 * HashTableFreeUnlinkedEntry(entry); // <- This does not need to lookup again.

dictEntry *HashTableUnlink(dict *d, const void *key) {
    return dictGenericDelete(d,key,1);
}

/* You need to call this function to really free the entry after a call
 * to HashTableUnlink(). It's safe to call this function with 'he' = NULL. */
