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.

*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.
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 #%d0 Handler(%d) Overflow at %p! vector=%#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]);}
