TAU_PROFILE_DECLARE_TIMER (3)

C: TAU_PROFILE_DECLARE_TIMER(Profiler timer);

Because C89 does not allow mixed code and declarations, TAU_PROFILE_TIMER can only be used once in a function. To declare two timers in a C function, use TAU_PROFILE_DECLARE_TIMER and TAU_PROFILE_CREATE_TIMER.

C :

int f1(void) {
  TAU_PROFILE_DECLARE_TIMER(t1);
  TAU_PROFILE_DECLARE_TIMER(t2);

  TAU_PROFILE_CREATE_TIMER(t1, "timer1", "", TAU_USER);
  TAU_PROFILE_CREATE_TIMER(t2, "timer2", "", TAU_USER);

  TAU_PROFILE_START(t1);
  ...
  TAU_PROFILE_START(t2);
  ...
  TAU_PROFILE_STOP(t2);
  TAU_PROFILE_STOP(t1);
  return 0;
}
