C++ API to get the private and virtual bytes consumed by a process

Is there 开发者_开发百科an API provided by Microsoft to get the private and virtual bytes consumed by a process ?

GetProcessMemoryInfo could be of great use.

To complement the answer by DumbCoder which amongst others gives you physical memory usage, you should also take a look at GlobalMemoryStatusEx.

Here you can find the definition of virtual bytes according to Microsoft and how you can derive it as a simple difference from two counters that GlobalMemoryStatusEx provides.

Notes of caution:

• The function GlobalMemoryStatusEx has mixed purpose since it provides information about the system as a whole and information specific to the calling process, e.g. virtual memory usage.
• Read/apply the API carefully otherwise you can end up with broken counters.
