Probably a simple one.
Basically I am retrieving a number from a file - setting a variable against it and then incrementing this by 1 and using this as an entry number in a log file for messages. I need the variable to re-evalute itself each time I call it so I get the latest number in the file -... (1 Reply)

PAPI_get_overflow_event_index(3) PAPI 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
@param EventSet
an integer handle to a PAPI event set as created by PAPI_create_eventset
@param overflow_vector
a vector with bits set for each counter that overflowed.
This vector is passed by the system to the overflow handler routine.
@param *array
an array of indexes for events in EventSet.
No more than *number indexes will be stored into the array.
@param *number
On input the variable determines the size of the array.
On output the variable contains the number of indexes in the array.
@retval 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.
@retval PAPI_ENOEVST
The EventSet specified does not exist.
@par 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]);}
