Keys and values - * must be strings. - * - * The exact library used depends on how Ruby was compiled. It could be any - * of the following: - * - * - The original ndbm library is released in 4.3BSD. - * It is based on dbm library in Unix Version 7 but has different API to - * support multiple databases in a process. - * - {Berkeley DB}[http://en.wikipedia.org/wiki/Berkeley_DB] versions - * 1 thru 5, also known as BDB and Sleepycat DB, now owned by Oracle - * Corporation. - * - Berkeley DB 1.x, still found in FreeBSD and OpenBSD. - * - {gdbm}[http://www.gnu.org/software/gdbm/], the GNU implementation of dbm. - * - {qdbm}[http://fallabs.com/qdbm/index.html], another open source - * reimplementation of dbm. - * - * All of these dbm implementations have their own Ruby interfaces - * available, which provide richer (but varying) APIs. - * - * = Cautions - * - * Before you decide to use DBM, there are some issues you should consider: - * - * - Each implementation of dbm has its own file format. Generally, dbm - * libraries will not read each other's files. This makes dbm files - * a bad choice for data exchange. - * - * - Even running the same OS and the same dbm implementation, the database - * file format may depend on the CPU architecture. For example, files may - * not be portable between PowerPC and 386, or between 32 and 64 bit Linux. - * - * - Different versions of Berkeley DB use different file formats. A change to - * the OS may therefore break DBM access to existing files. - * - * - Data size limits vary between implementations. Original Berkeley DB was - * limited to 2GB of data. Dbm libraries also sometimes limit the total - * size of a key/value pair, and the total size of all the keys that hash - * to the same value. These limits can be as little as 512 bytes. That said, - * gdbm and recent versions of Berkeley DB do away with these limits. - * - * Given the above cautions, DBM is not a good choice for long term storage of - * important data. It is probably best used as a fast and easy alternative - * to a Hash for processing large amounts of data. - * - * = Example - * - * require 'dbm' - * db = DBM.open('rfcs', 666, DBM::CREATRW) - * db['822'] = 'Standard for the Format of ARPA Internet Text Messages' - * db['1123'] = 'Requirements for Internet Hosts - Application and Support' - * db['3068'] = 'An Anycast Prefix for 6to4 Relay Routers' - * puts db['822'] - */ -void -Init_dbm(void) -{ - rb_cDBM = rb_define_class("DBM", rb_cObject);
