pjlib - How do I enum all keys in a pjsip hashtable?
Hi, all:
How can I enum all keys in a pjsip hashtable? I didn't find such functions in pjlib hashtable's manual. And I tried to get keys directly from pj_hash_entry, but the "keys" member is not open to the outside. So, how can I do this?
Thanks a lot.

Use pj_hash_first() to get an iterator then use pj_hash_next() with iterator as input.

Thanks, peteryzwei. But pj_hash_first/pj_hash_next/pj_hash_this can only enum values in the hashtable. I wanna checkout all keys. Any other suggestions?

Super,
since pj_hash_entry is defined in hash.c, the key is opaque to the caller. To get around this, I suggest adding the following function to hash.c and updating hash.h.
//hash.c
//get the key from the iterator. keyBuf MUST be big enough to hold the key.
pj_uint32 getKey(pj_hash_iterator_t *iterator, char *keyBuf) {
memcpy(keyBuf, iterator->entry->key, iterator->entry->keylen);
return iterator->entry->keylen;
}
//hash.h
pj_uint32 getKey(pj_hash_iterator_t *iterator, char *keyBuf);

Thanks, peteryzwei. I got it. I just wanna make sure whether there is some APIs I missed which can get the keys of pj hashtable. Actually, I don't wanna change the source codes of pjsip cause this brings additional code "merge" works while upgrading.
Anyway, thanks a lot.
