dbh_set_size(3) DBHashTables Programmers' Manual dbh_set_size(3) - NAME dbh_set_size, dbh_set_recordsize - set maximum or current record size SYNOPSIS #include <dbh.h> int dbh_set_size (DBHashTable *dbh, FILE_POINTERsize); void dbh_set_recordsize (DBHashTable *dbh, int record_size ); DESCRIPTION Function dbh_set_size defines the maximum amount of memory to be allo- cated to the DBHashTable records. This is nonvolatile information which need to be set only once. The default is 1024 bytes. Function dbh_set_recordsize sets the recordsize of the the data in the current DBHashTable and is called implicitly by calling dbh_set_data It is very important to call this function if dbh_set_data is not used. Unpredictable results will follow if record_size is not set. DB- HashTable records are variable in length, so use this function at least once if you are planning to use fixed length records. Parameter record_size is the amount of bytes to be reserved for the current DB- HashTable record data. RETURN VALUE dbh_set_size returns 0 on error, 1 otherwise. dbh_set_recordsize returns the amount of bytes in the current DB- HashTable record.
