• Memory used by current running application ?

I think Qt should hav

Answer 1

Much better on POSIX OSes (Linux, Solaris, perhaps latest MacOS...) :

• getrusage(...) secially look at ru_maxrss.
• getrlimit(...) but I did not find any usefull info into.
• sysconf(...) : _SC_PAGESIZE, _SC_PHYS_PAGES, _SC_AVPHYS_PAGES
• sysinfo(...) : totalram, freeram, sharedram, totalswap,...

So much treasures on POSIX computers not available on Windows.
