返回值 (Return Value)

例子 (Example)

以下是显示其基本用法的示例代码 -

#!/usr/bin/perl
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;

执行上述代码时，会产生以下结果 -

Name  = ip-50-62-147-141.ip.secureserver.net
Aliases  = ip-50-62-147-141 localhost.secureserver.net localhost.localdomain localhost
Addr Type  = 2
Length  = 4
Addrs  = 
Name  = ip-50-62-147-141.ip.secureserver.net
Aliases  = ip-50-62-147-141 localhost.secureserver.net localhost.localdomain localhost
Addr Type  = 2
Length  = 4
Addrs  =
