+ void *private_data),
+ void *private_data);
+
+ Hand a record to a parser function without allocating it.
+
+ This function is meant as a fast tdb_fetch alternative for large records
+ that are frequently read. The "key" and "data" arguments point directly
+ into the tdb shared memory, they are not aligned at any boundary.
+
+ WARNING: The parser is called while tdb holds a lock on the record. DO NOT
+ call other tdb routines from within the parser. Also, for good performance
+ you should make the parser fast to allow parallel operations.
+
+ tdb_parse_record returns -1 if the record was not found. If the record was
+ found, the return value of "parser" is passed up to the caller.
