批处理读取INI文件

@echo off
:::::::::INI文件读取::::::::::::::::::::::
::使用方法:       ::
::    inifile iniFilePath [section] [item]   ::
::例子:        ::
:: inifile c:\boot.ini     ::
:: 读取c:\boot.ini的所有[section]    ::
:: inifile c:\boot.ini "[boot loader]"   ::
:: 读取c:\boot.ini [boot loader]段的内容   ::
:: inifile c:\boot.ini "[boot loader]" timeout  ::
:: 显示c:\boot.ini [boot loader]段 timeout的值  ::
:: 新增设置变量的功能,只需将下面的setvar=0改为1即可 ::
::::::::::::::::::::::::::::::::::::::::::::::::::::::::
set setvar=0
::当有指定[item]参娄并且setvar值为1时就将[item]的值设为变量[item]
::例子inifile c:\boot.ini "[boot loader]" timeout 就可以得到一个%timeout%的变量
