Detailed Description

The ProcessMonitor class grants access to processes memory and CPU usage.

Since querying process specific information is not standardized in C++, Only a Linux solution is provided yet.

Source of the Information

The pid is obtained via getpid() numThreads and memoryUsage is obtained by parsing /proc/self/stats memoryUsage is obtained by reading a piped 'ps' processes output since querying information an in particular waiting for 'ps' output takes some time, all the information is collected in a dedicated thread. numCPUs is queried once at construction time by parsing /proc/processor allCPU usage is also queried by parsing the piped 'ps' output

Callbacks

Since sometimes, an application wants to do something, when new information is available, a callback mechanism is provided as well. Simply register an icl::Function instance that is then called whenever a new set of data is available.
