GNU Gdbm Reference Manual

Hướng dẫn sử dụng GNU GDBM Reference

GNU dbm (or GDBM, for short) is a library of database functions that use extensible hashing and work similar to the standard UNIX dbm. These routines are provided to a programmer needing to create and manipulate a hashed database.

The basic use of GDBM is to store key/data pairs in a data file. Each key must be unique and each key is paired with only one data item.

The Gdbm Reference Manual provides beginners with a simple introduction to the basics, and experts will find advanced details they need.
