for回圈執行第一次的程序中，getEyeCornerLbp256or59()函式執行完之后，file->num就變成一個很大的負值。在這個函式執行之前的程式中file->num的值很正常，指的是檔案夾里圖片的數量。求助，一天都沒找到問題所在，小妹字在此感激涕零。。。

getEyeCornerLbp256or59 這個函式處理是否有問題，或者你引數傳遞等不正確，導致它修改或者越界寫入了垃圾資料uj5u.com熱心網友回復：
變數初始化試試uj5u.com熱心網友回復：
把代碼再精簡一些，注釋掉一部分代碼 ，看看問題是出現在什么地方，先定位出出題出在哪句代碼或者哪幾句上，才好解決問題uj5u.com熱心網友回復：
