GDBM_File(3perl)                 Perl Programmers Reference Guide                GDBM_File(3perl)

NAME
       GDBM_File - Perl5 access to the gdbm library.

SYNOPSIS
           use GDBM_File ;
           tie %hash, 'GDBM_File', $filename, &GDBM_WRCREAT, 0640;
           # Use the %hash array.
           untie %hash ;

DESCRIPTION
       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 "delete" the current item from a
       GDBM_File tied hash while iterating over it with "each".  This is a limitation of the gdbm
       library.

AVAILABILITY
       gdbm is available from any GNU archive.  The master site is "ftp.gnu.org", but you are
       strongly urged to use one of the many mirrors.  You can obtain a list of mirror sites from
       <http://www.gnu.org/order/ftp.html>.

SECURITY AND PORTABILITY
       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 "libgdbm".

       A maliciously crafted file might cause perl to crash or even expose a security
       vulnerability.

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.
