|
|
GDBM_File - Perl5 access to the gdbm library.
|
|
|
|
=head1 SYNOPSIS
|
|
|
|
use GDBM_File ;

=head1 DESCRIPTION
|
|
|
|
B<GDBM_File> is a module which allows Perl programs to make use of the
|
|
facilities provided by the GNU gdbm library. If you intend to use this
|
|
module you should really have a copy of the gdbm manualpage at hand.
|
|
|
|
Most of the libgdbm.a functions are available through the GDBM_File
|
|
interface.
|
|
|
|
=head1 AVAILABILITY
|
|
|
|
Gdbm is available from any GNU archive. The master site is
|
|
C<prep.ai.mit.edu>, but your are strongly urged to use one of the many
|
|
mirrors. You can obtain a list of mirror sites by issuing the
|
|
command C<finger fsf@prep.ai.mit.edu>.
|
|
|
|
=head1 BUGS
|
|
|
|
The available functions and the gdbm/perl interface need to be documented.
|
|
