MirOS Manual: DBM_Filter::null(3p)

DBM_Filter::null(Perl Programmers Reference GDBM_Filter::null(3p)


     DBM_Filter::null -- DBM Filter to force null termination


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

         $db = tie %hash, ...


     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.
