PAPI_get_overflow_event_index(3) PAPI PAPI_get_overflow_event_index(3)NAMEPAPI_get_overflow_event_index-
converts an overflow vector into an array of indexes to overflowing
events
SYNOPSISDetailed Description
Parameters:
EventSet an integer handle to a PAPI event set as created by
PAPI_create_eventset
overflow_vector a vector with bits set for each counter that
overflowed. This vector is passed by the system to the overflow
handler routine.
*array an array of indexes for events in EventSet. No more than
*number indexes will be stored into the array.
*number On input the variable determines the size of the array. On
output the variable contains the number of indexes in the array.
Return values:
PAPI_EINVAL One or more of the arguments is invalid. This could
occur if the overflow_vector is empty (zero), if the array or
number pointers are NULL, if the value of number is less than one,
or if the EventSet is empty.
PAPI_ENOEVST The EventSet specified does not exist.
Examples
void handler(int EventSet, void *address, long_long overflow_vector, void *context){
int Events[4], number, i;
int total = 0, retval;
printf('Overflow #%d Handler(%d) Overflow at %p! vector=0x%llx0,
total, EventSet, address, overflow_vector);
total++;
number = 4;
retval = PAPI_get_overflow_event_index(EventSet,
overflow_vector, Events, &number);
if(retval == PAPI_OK)
for(i=0; i<number; i++) printf('Event index[%d] = %d', i, Events[i]);}
