PAPI_get_overflow_event_index(3)

NAME
PAPI_get_overflow_event_index -

converts an overflow vector into an array of indexes to overflowing events

SYNOPSIS

Detailed 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%llx,
            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]);}
