- * Find an entry in the database and hand the record's data to a parsing

- * should be fast and should not block on other syscalls.
- *
- * DON'T CALL OTHER TDB CALLS FROM THE PARSER, THIS MIGHT LEAD TO SEGFAULTS.
- *
- * For mmapped tdb's that do not have a transaction open it points the parsing
- * function directly at the mmap area, it avoids the malloc/memcpy in this
- * case. If a transaction is open or no mmap is available, it has to do
- * malloc/read/parse/free.
- *
- * This is interesting for all readers of potentially large data structures in
- * the tdb records, ldb indexes being one example.
- *
- * Return -1 if the record was not found.
