- dbh_load(3) DBHashTables Programmers' Manual dbh_load(3) NAME dbh_load, dbh_load_address, dbh_load_parent, dbh_load_child - load a DB- HashTable record to memory SYNOPSIS #include <dbh.h> FILE_POINTER dbh_load (DBHashTable *dbh); unsigned char dbh_load_address (DBHashTable *dbh, FILE_POINTERcurrentseek); FILE_POINTER dbh_load_parent (DBHashTable *dbh); FILE_POINTER dbh_load_child (DBHashTable *dbh, unsigned char key_index); DESCRIPTION dbh_load will load a record using the currently set key. This function will also load erased values, except that it will return 0. dbh_load_address will load a record from hash table directly from byte off- set currentseek. dbh_load_parent will load the parent of the currently loaded record. dbh_load_child will load the first child of the currently loaded record, on branch identified by key_index. Since the number of childs (or branches) of each record is variable, this may be tricky. Top level records have DBH_KEYLENGTH branches. Lower level records have less. Each byte of a key represents a branch on top level records. RETURN VALUE dbh_load_address will return 0 on error, number of branches otherwise. dbh_load, dbh_load_parent, dbh_load_child will return 0 on error, byte off- set of loaded record otherwise.
