C++ STL with jemalloc

Question

How is it possible to use C++ STL containers with jemalloc (or any other malloc implementation)?

Is it as simple as include jemalloc/jemalloc.h

Answer 1

If you want to replace malloc everywhere in your program (which I wanted to and also seems the only logical solution), then all you have to do is link against it.

So, if you use gcc then all you have to do is:

g++ yourprogram.cpp -ljemalloc

But, if it's not possible, then you have to use jemalloc via another functions e.g. je_malloc and je_free, and then you have to overload the new and delete operators.

There's no need for including any header if you don't use implementation-specific features (statistics, mostly).
