Elements: Oprofile Interface (3)

Using the module entails the following phases

Initialization
Prospect first finds the module and loads it if not loaded. Then we open the hashmap device, if successful, we own the device. We then set up a default configuration using CPU_CLK_UNHALTED event with a default frequency of 200 Hz. If the counters were active in the module, prospect does not change them.

Prospect next harvests information in /proc for all other processes running on the system and builds the system model.
