在最短的时间内释放记忆 [英] freeing memory in shortest time
问题描述
你好，
我有一个指向主结构的指针，它又包含了
结构，枚举，char，int，float和复杂的结构。
当我释放主结构的所有内容时，它花了我很多时间（因为我必须循环确定数据类型和释放
吧）。有没有想法在
最短的时间内释放结构的所有内容。
Hello,
I have a pointer to a main structure which again consists of
structures, enums, char, int, float and again complex structures.
When i free all the contents of the main structure, it takes me a lot
of time (since i have to loop determining the data type and freeing
it). Is there any idea to free all the contents of the structure in
shortest possible time.
推荐答案
或者我应该切换到静态内存而不是???在那种情况下
应该小心谨慎。
Pl建议
Or probably should i switch to static memory instead??? In that case
what care should be taken.
Pl advice

您可以尝试将结构设为静态。或者你可以尝试使用每个结构的动态内存指针的单独缓存
元素。这将消耗额外的内存，但将消除
需要遍历结构以释放它的所有组件。
无论如何，我怀疑遍历这个结构将是你最严重的瓶颈，特别是如果你一次性完成所有这些。
You might try making the structure static. Or you might try having a
separate cache of all the pointers to dynamic memory for each structure
element. This will consume additional memory, but will eliminate the
need to traverse the structure to free all it''s components.
In anycase, I doubt that traversing the structure is going to be your
most serious bottleneck, particularly if you do it all at once.

好吧，退出（0）就可以了。但是我很想知道你为什么认为它花了很多时间才花了很多钱。如今计算机速度非常快。这真的是你的程序的
瓶颈吗？分析告诉你什么？

Well, exit(0) will do it. But I''m curious to know why you think it''s taking
a lot of time. Computers are pretty fast nowadays. Is this really the
bottleneck for your program? What did profiling tell you?
