dcache is a database library implementing a persistent first-in-first-out cache. The database (or `cache) size limits are configured at creation time, and as soon as they are reached the oldest records are automatically removed. dcache library has a number of commandline tools for managing the database. dcache is a disk based caching database in a single file containing a header and fixed sized hash and data space. The header holds variables and constants describing the database. The hash table holds pointers into the data area and hashes of the keys. The hash function used is a crc32. The data area consists of the data, the key, a 64bit number with application defined use, and two 32bit numbers holding key and data lengths. The header and hash table are mapped into process address space using the mmap(2) system call. The data area is not memory mapped, thus allowing to handle multi-gigabyte files even on systems with a 32bit address space..
