描述 (Description)
此函数告诉系统您不再期望使用gethostent从hosts文件中读取条目。
语法 (Syntax)
以下是此函数的简单语法 -
endhostent
返回值 (Return Value)
此函数不返回任何值。
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 =
