使用C ++清理程序测量动态内存使用情况

Question

我正在寻找一种简单的方法来衡量C ++应用程序使用的总内存。我知道valgrind，但最近我遇到了C ++的内存消毒剂。是否可以使用任何清理程序测量C ++可执行二进制文件使用的最大堆/堆栈内存？

Answer 1

使用time -v可以为您提供有关应用程序的大量有用信息：

    System time (seconds): 0.00
    Percent of CPU this job got: 0%
    Elapsed (wall clock) time (h:mm:ss or m:ss): 0:05.00
    Average shared text size (kbytes): 0
    Average unshared data size (kbytes): 0
    Average stack size (kbytes): 0
    Average total size (kbytes): 0
    Maximum resident set size (kbytes): 2144
    Average resident set size (kbytes): 0
    Major (requiring I/O) page faults: 0
    Minor (reclaiming a frame) page faults: 179
    Voluntary context switches: 2
    Involuntary context switches: 1
    Swaps: 0
    File system inputs: 0
    File system outputs: 0
    Socket messages sent: 0
    Socket messages received: 0
