+ * A process is an executing unit in an operating system with its own address
+ * space. Every process can be identified with a unique identifier called PID.
+ * To get a PID of the currently running process call
+ * p_process_get_current_pid(). To check whether a process with a given PID is
+ * running up use p_process_is_running().
