示例

以下示例程式碼展示了其基本用法 -

while( ($name, $aliases, $addrtype, $length, @addrs) = gethostent() ) {
   print "Name  = $name\n";
   print "Aliases  = $aliases\n";
   print "Addr Type  = $addrtype\n";
   print "Length  = $length\n";
   print "Addrs  = @addrs\n";
}

sethostent(1);

while( ($name, $aliases, $addrtype, $length, @addrs) = gethostent() ) {
   print "Name  = $name\n";
   print "Aliases  = $aliases\n";
   print "Addr Type  = $addrtype\n";
   print "Length  = $length\n";
   print "Addrs  = @addrs\n";
}

endhostent();  # Closes the database;

Aliases  = ip-50-62-147-141 localhost.secureserver.net localhost.localdomain localhost
Addr Type  = 2
