7.11 dbhash -- DBM-style interface to the BSD database library
Availability: Unix, Windows.
The dbhash module provides a function to open databases using
the BSD db library. This module mirrors the interface of the
other Python database modules that provide access to DBM-style
databases. The bsddb module is required
to use dbhash.
This module provides an exception and a function:
- Exception raised on database errors other than KeyError. It is a synonym for bsddb.error.
-
Open a
dbdatabase and return the database object. The path argument is the name of the database file.The flag argument can be
'r'(the default),'w','c'(which creates the database if it doesn't exist), or'n'(which always creates a new empty database). For platforms on which the BSDdblibrary supports locking, an "l" can be appended to indicate that locking should be used.The optional mode parameter is used to indicate the Unix permission bits that should be set if a new database must be created; this will be masked by the current umask value for the process.
