Event CountersProcedural Interface

- The event specifiers e0 and e1 can also be set (or overruled) at run time by the environment variables
  - T5_EVENT0 and T5_EVENT1
- link with -lperfex
- the counter values c0 and c1 are 64 bit integers

int start_counters(int e0, int e1);

int read_counters( int e0, long long *c0,

int e1, long long *c1);

int print_counters(int e0, long long c0,

int e1, long long c1);
