# GDBM_File.pm -- Perl 5 interface to GNU gdbm library.
=head1 NAME
GDBM_File - Perl5 access to the gdbm library.
=head1 SYNOPSIS
use GDBM_File ;
tie %hash, 'GDBM_File', $filename, &GDBM_WRCREAT, 0640;
# Use the %hash array.
untie %hash ;
=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.
Unlike Perl's built-in hashes, it is not safe to C<delete> the current
item from a GDBM_File tied hash while iterating over it with C<each>.
This is a limitation of the gdbm library.
=head1 AVAILABILITY
gdbm is available from any GNU archive. The master site is
C<ftp.gnu.org>, but you are strongly urged to use one of the many
mirrors. You can obtain a list of mirror sites from
L<http://www.gnu.org/order/ftp.html>.
=head1 SECURITY AND PORTABILITY
B<Do not accept GDBM files from untrusted sources.>
GDBM files are not portable across platforms.
The GDBM documentation doesn't imply that files from untrusted sources
can be safely used with C<libgdbm>.
A maliciously crafted file might cause perl to crash or even expose a
security vulnerability.
=head1 BUGS
The available functions and the gdbm/perl interface need to be documented.
The GDBM error number and error message interface needs to be added.
