示例

以下示例代码展示了其基本用法 −

#!/usr/bin/perl

use Socket;

while ( ($name, $aliases, $addrtype, $net)  = getnetent() ) {

   print "Name = $name\n";
   print "Aliases = $aliases\n";
   print "Addrtype = $addrtype\n";
   print "Net = $net\n";
}

setnetent(1); # Rewind the database;

while ( ($name, $aliases, $addrtype, $net)  = getnetent() ) {

   print "Name = $name\n";
   print "Aliases = $aliases\n";
   print "Addrtype = $addrtype\n";
   print "Net = $net\n";
}

endnetent();  # Closes the database;

执行以上代码后，将产生以下结果 −

Name = default
Aliases = 
Addrtype = 2
Net = 0
Name = loopback
Aliases = 
Addrtype = 2
Net = 2130706432
Name = link-local
Aliases = 
Addrtype = 2
Net = 2851995648
Name = default
Aliases = 
Addrtype = 2
Net = 0
Name = loopback
Aliases = 
Addrtype = 2
Net = 2130706432
Name = link-local
Aliases = 
Addrtype = 2
Net = 2851995648
