c++ - Cgroup usage to limit resources -

my goal: provide user way limit resources cpu, memory given process (c++).

so suggested me utilize cgroups looks ideal utility.

after doing research have concern:

when utilize memory.limit_in_bytes limit memory usage given process, there way handle out of memory exception in process? see control groups provide parameter called "memory.oom_control" when enabled, kills process requesting more memory allowed. when disabled pauses process.

i want way let process know requesting more memory expected , should throw out of memory exception. process gracefully exits.

does cgroups provide such kind of behaviour?

also cgroup available in flavour of linux? interested in rhel 5+, centos 6+ , ubuntu 12+ machines.

any appreciated.

thanks

all processes in recent releases run inside cgroup, default one. if create new cgroup , migrate process new cgroup, works before using constraints new cgroup. if process allocates more memory permitted, gets enospc or malloc failure presently does.
