关于FindCmdLineSwitch函数的使用

[Ascn]

谁知道这个函数怎么用的？
Determines whether a string was passed as a command line argument to the application.

Unit

SysUtils

Category

command line utilities

function FindCmdLineSwitch(const Switch: string; SwitchChars: TSysCharSet; IgnoreCase: Boolean): Boolean;

Description

FindCmdLineSwitch determines whether the string specified by the Switch parameter was passed as a command line argument to the application. SwitchChars identifies valid argument-delimiter characters (such as "-"and "/"). The IgnoreCase parameter controls whether a case-sensitive or case-insensitive search is performed.

由于没有找到例子代码，我不知道它具体怎么用，因为我想让自己的程序可传入多个
参数，各参数不分顺序，如下格式：
myApp.exe -U:user -P:pwd
或者：　myApp.exe -U user -P pwd

麻烦给点具体代码，必须要带switch处理的。谢谢
