DBM_Filter::null(3)


DBM_Filter::null


SYNOPSIS

      use SDBM_File; # or DB_File, or GDBM_File, or NDBM_File, or ODBM_File

      use DBM_Filter ;


      $db = tie %hash, ...

      $db->Filter_Push('null');


DESCRIPTION

  This filter ensures that all data written to the DBM file is null

  terminated. This is useful when you have a perl script that needs to

  interoperate with a DBM file that a C program also uses. A fairly common

  issue is for the C application to include the terminating null in a string

  when it writes to the DBM file. This filter will ensure that all data

  written to the DBM file can be read by the C application.


SEE ALSO

  DBM_Filter, perldbmfilter
