dbh_create(3) DBHashTables Programmers' Manual dbh_create(3) - NAME dbh_open, dbh_openR, dbh_create - open or create a new DBHashTable SYNOPSIS #include <dbh.h> DBHashTable *dbh_open(constchar*path); DBHashTable *dbh_openR(constchar*path); DBHashTable *dbh_create (const char *path, unsigned char key_length); DESCRIPTION dbh_open () opens an existing DBHashTable at path in read/write mode while dbh_openR () will open in read-only mode. To create, initialize and open a new DBHashTable in read/write mode, dbh_create () is used. key_length is the fixed length of the record access key and must be less than 256. This only need be specified when the DBHashTable is cre- ated and initialized. RETURN VALUE On success, a pointer to a newly initialized and open DBHashTable or NULL if it fails (and errno is set appropriately). NOTES This function will overwrite any file with the specified path includ- ing any previous DBH file. Cuantified keys assure that large DBHashes are spread out optimally.
