perl function dbmclose

The dbmclose function in Perl is used to close a DBM database file that was previously opened using the dbmopen function. Here's an example of how to use dbmclose:

use DB_File;

# Open a DBM database file
my %db;
my $filename = 'mydatabase.db';
dbmopen(%db, $filename, 0666) or die "Cannot open $filename: $!";

# Do some operations on the database...

# Close the database file
dbmclose(%db);

In this example, the DB_File module is used to open a DBM database file named "mydatabase.db" using the dbmopen function. Once the database is open, various operations can be performed on it. Finally, the dbmclose function is used to close the database file.

It's important to note that any changes made to the database while it's open will be written to disk when the database is closed. Therefore, it's good practice to always close the database file when you're finished using it.
