ODBM_File 5.8.8

ODBM_File is a Perl module to allow tied access to odbm files. SYNOPSIS use Fcntl; # For O_RDWR, O_CREAT, etc. use ODBM_File; # Now read and change the hash $h{newkey} = newvalue; print $h{oldkey}; ... untie %h; ODBM_File establishes a connection between a Perl hash variable and a file in ODBM_File format;. You can manipulate the data in the file just as if it were in a Perl hash, but when your program exits, the data will remain in the file, to be used the next time your program runs. Use ODBM_File with the Perl built-in tie function to establish the connection between the variable and the file. The arguments to tie should be: The hash variable you want to tie. The string "ODBM_File". (Ths tells Perl to use the ODBM_File package to perform the functions of the hash.) The name of the file you want to tie to the hash. Flags. Use one of: O_RDONLY Read-only access to the data in the file. O_WRONLY Write-only access to the data in the file. O_RDWR Both read and write access. If you want to create the file if it does not exist, add O_CREAT to any of these, as in the example. If you omit O_CREAT and the file does not already exist, the tie call will fail. The default permissions to use if a new file is created. The actual permissions will be modified by the users umask, so you should probably use 0666 here. (See "umask" in perlfunc.).
