本文介绍了Windows下使用UMDH工具和Linux下通过/proc/pid/smaps文件来查看进程的堆内存使用情况的方法，并提供了内存分配大小及调用堆栈等详细信息。此外，还提到了用于检测内存泄漏的工具Purify和valgrind。

Heap memory usage footprint:

Windows: Microsoft has UMDH tool to dump memory usage in heap. It contains the memory allocation, size and where(call statck to alloc this memory)

For example:

490 bytes + 30 at 1433D0 by BackTrace16
78EDD036
78D58EE6
78D57BAC
78D58E9E
78D57AC0
78EDEF73
78ED7946
78ED62D8
78ED6416
78EF3925
78D59630

628 bytes + 38 at 143890 by BackTrace17
78EDD036
78D58F18
78D57BAC
78D58E9E
78D57AC0
78EDEF73
78ED7946
78ED62D8
78ED6416
78EF3925
78D59630

Linux: /proc/pid/smaps or /proc/pid/maps has memory allocation and size information, but no call stack. smaps had more detail information than maps.

For example:
