      5 /*	mkmap_cdb 3
      6 /* SUMMARY
      7 /*	create or open database, CDB style
      8 /* SYNOPSIS
      9 /*	#include <dict_cdb.h>

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