5 /* create or open database, CDB style

12 /* DESCRIPTION
13 /* This module implements support for creating DJB's CDB "constant
14 /* databases".
15 /*
16 /* mkmap_cdb_open() take a file name, append the ".cdb.tmp" suffix,
17 /* create the named DB database. On close, this file renamed to
18 /* file name with ".cdb" suffix appended (without ".tmp" part).
19 /* This routine is a CDB-specific helper for the more
20 /* general mkmap_open() interface.
21 /*
22 /* All errors are fatal.
23 /* SEE ALSO
24 /* dict_cdb(3), CDB dictionary interface.
