c - 为什么我的程序有内存泄漏检查错误？

Question

当我使用它时

valgrind --leak-check=yes ./Main

我有大约 185236 个错误。它说:

xx bytes in x blocks are possibly lost in loss record xxxx of xxxx

这是我的代码:

Node InsertString(Head head, Node tree, char* data) {
    if (tree == NULL) {
        tree = malloc(sizeof (struct TreeNode)); //Error

        if (tree == NULL) {
            printf("Out of Space!\n");
        } else {
             tree->theData = malloc(sizeof (char) * strlen(data));//Error
            strcpy(tree->theData, data);
        }
    } else {
            if (strcmp(data, tree->theData) < 0) {
                tree->Left = InsertString(head, tree->Left, data); //Error
            } else {
                if (strcmp(data, tree->theData) > 0) {
                    tree->Right = InsertString(head, tree->Right, data);//Error
                }
            }
        } 

    }
    return tree;
}

谢谢!

你有没有调用过free来释放你用malloc分配的内存？

如果不是，好吧，那么你正在泄漏所有的内存。
