#The dbmopen function associates a DBM database with a Perl hash or associative array.
|
|
#The dbmopen function takes the following syntax:
|
|
|
|
#dbmopen(%hash, $database, $mode) or die "Cant open \"$database\" due to $!";
|
|
|
|
#The $mode value contains the file permissions used to create the DBM file if it doesnt exist.
|
|
|
|
#When youre done with a DBM database, call dbmclose to close it:
|
|
#dbmclose(%hash)
|
|
#You pass the hash to dbmclose, not the database file name.
