8 /* SYNOPSIS

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
