# 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.
