/*-----------------------------------------------------------------------------
注意：如果文件以t即text方式打開，則回車換行兩個字符在input時被當作一個字符處理，
因此fgets()得到的一行字符串尾部只有一個換行符而沒有回車符，而如果是binary
方式打開則一行字符尾部同時有回車換行兩個字符，打開方式的不同直接影響fgets
讀入一行后刪除行尾部控制字符的操作，如果是text方式，只要刪除換行符號即可，
如果是binary方式，則要刪掉兩個控制字符。以下對兩個控制字符是否存在都進行
判斷，可以同時適應text和binary兩種模式,也就能同時適應Windows下和Unix兩種
不同格式的文本文件(unix文本文件行末只有一個換行符，即0A,沒有回車符)
后續記錄: fopen()中打開模式里的"t"是微軟自己定義的，Ansi C 只支持 "b"模式
----------------------------------------------------------------------------*/
if(fgets(lpszLineBuf, iLen, IniFile) != NULL) //fgets()函數遇到第一個換行符(0x0A)后結束(包括換行符),然后在尾部追加一個NULL后返回,因此換行符總是倒數第二個字符
