\modulesynopsis{Guess which DBM-style module created a given database.}
|
|
|
|
|
|
The single function in this module attempts to guess which of the
|
|
several simple database modules available--\refmodule{dbm},
|
|
\refmodule{gdbm}, or \refmodule{dbhash}--should be used to open a
|
|
given file.
|
|
|
|
\begin{funcdesc}{whichdb}{filename}
|
|
Returns one of the following values: \code{None} if the file can't be
|
|
opened because it's unreadable or doesn't exist; the empty string
|
|
(\code{''}) if the file's format can't be guessed; or a string
|
|
containing the required module name, such as \code{'dbm'} or
|
|
\code{'gdbm'}.
