cnid_dbd_find()

extern

Backend implementation of cnid_find() for the DBD daemon backend.

Parameter validation is performed once in the wrapper at libatalk/cnid/cnid.c. This function trusts that cdb, name, namelen, buffer and buflen are sane and focuses on driving the paginated SEARCH RPC to cnid_dbd.

The single cleanup path (goto out) ensures signal-handler restoration and more_available write-back happen in exactly one place — every error arm goes through it. *more_available is set to true if the result set was truncated by the daemon offset cap, the wall-clock deadline, signal-induced abort, or the buffer-fit guard; written only on success (the wrapper has already pre-zeroed it for error paths).
