Allows Perl programs to make use of the
facilities provided by the GNU gdbm library.
Most of the libgdbm.a functions are available as methods of the
GDBM_File interface. See the
gdbm(3) manpage and the description of DB_File in
this chapter. The following is an example of the use of GDBM_File:
use GDBM_File; tie %hash, "GDBM_File", $filename, &GDBM_WRCREAT, 0644); # read/writes of %hash are now read/writes of $filename untie %hash;
