Re: [Boost-users] Help in calculating the size of a boost::unordered_map

Thanks for all your replies Chris, Jon and Ian! I will implement a custom allocator and pass it to the unordered_map. But for starters it looks like the Valgrind solution seems easiest. I am working on Windows using Visual C++, compiler VC12. I will look for Valgrind alternatives for Windows. Thanks, -R On Nov 8, 2016 3:13 AM, "Ian Bruntlett" wrote:

Hi,

I would like to calculate the size of my filled up boost::unordered_map including the house keeping. I was thinking of sizeof(boost:unordered_map mymap). I asked this question on stackoverflow but they say that wont help. Can somebody tell me an easy way to find the size including the housekeeping that it takes?

The boost::unordered_map stores a std::string as the key and a pointer to my class object as the value.

Not sure which platform you are doing this on but if you are using some kind of Linux then this site http://valgrind.org/ might be useful

BW,

Ian
