=head1 DESCRIPTION |
| 15 |
|
| 16 |
B<GDBM_File> is a module which allows Perl programs to make use of the |
| 17 |
facilities provided by the GNU gdbm library. If you intend to use this |
| 18 |
module you should really have a copy of the gdbm manualpage at hand. |
| 19 |
|
| 20 |
Most of the libgdbm.a functions are available through the GDBM_File |
| 21 |
interface. |
| 22 |
|
| 23 |
=head1 AVAILABILITY |
| 24 |
|
| 25 |
gdbm is available from any GNU archive. The master site is |
| 26 |
C<ftp.gnu.org>, but you are strongly urged to use one of the many |
| 27 |
mirrors. You can obtain a list of mirror sites from |
| 28 |
http://www.gnu.org/order/ftp.html. |
| 29 |
|
| 30 |
=head1 BUGS |
| 31 |
|
| 32 |
The available functions and the gdbm/perl interface need to be documented. |
| 33 |
|
| 34 |
The GDBM error number and error message interface needs to be added. |
