语法

以下是此函数的简单语法-

endhostent

返回值

此函数不返回任何值。

例

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;

执行上述代码后,将产生以下输出-

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
