If RETCTX is not NULL, then the constructed context is returned in
*RETCTX so that getpubkey_next can be used to get subsequent
results. In this case, getkey_end() must be used to free the
search context. If RETCTX is not NULL, then RET_KDBHD must be
NULL.
If NAMELIST is not NULL, then a search query is constructed using
classify_user_id on each of the strings in the list. (Recall: the
database does an OR of the terms, not an AND.) If NAMELIST is
NULL, then all results are returned.
If PK is not NULL, the public key of the first result is returned
in *PK. Note: PK->REQ_USAGE must be valid!!! If PK->REQ_USAGE is
set, it is used to filter the search results. See the
documentation for finish_lookup to understand exactly how this is
used. Note: The self-signed data has already been merged into the
public key using merge_selfsigs. Free *PK by calling
release_public_key_parts (or, if PK was allocated using xfree, you
can use free_public_key, which calls release_public_key_parts(PK)
and then xfree(PK)).
If WANT_SECRET is set, then only keys with an available secret key
(either locally or via key registered on a smartcard) are returned.
If INCLUDE_UNUSABLE is set, then unusable keys (see the
documentation for skip_unusable for an exact definition) are
skipped unless they are looked up by key id or by fingerprint.
If RET_KB is not NULL, the keyblock is returned in *RET_KB. This
should be freed using release_kbnode().
If RET_KDBHD is not NULL, then the new database handle used to
conduct the search is returned in *RET_KDBHD. This can be used to
get subsequent results using keydb_search_next. Note: in this
case, no advanced filtering is done for subsequent results (e.g.,
WANT_SECRET and PK->REQ_USAGE are not respected).
This function returns 0 on success. Otherwise, an error code is
returned. In particular, GPG_ERR_NO_PUBKEY or GPG_ERR_NO_SECKEY
(if want_secret is set) is returned if the key is not found. */
