我有一個包含記錄的文件,想通過在項目內部調用sort來對它們進行排序。運行該程序時,一切似乎都很好,但是在嘗試使用valgrind檢查洩漏時,我遇到了很多錯誤。這是我用來執行的代碼: execlp(“ sort”,“ -g”,“結果”,(char *)NULL); 結果是我要整理的文件。 並且有錯誤。 == 27691 == == 27691 ==堆摘要: == 27691 ==在出口處使用:17個塊中的1,352字節 == 27691 ==堆總使用量:66個分配,49個釋放,44,055個字節分配 == 27691 == == 27691 == 1個塊中的16個字節肯定在6的丟失記錄中丟失了 == 27691 ==在0x4C2DB8F:malloc(在/usr/lib/valgrind/vgpreload_memcheck-amd64-linux.so) == 27691 ==通過0x4110C8:???
