💅 PAPI_get_overflow_event_index(3) 💅

okay bestie, welcome to the PAPI manual page for PAPI_get_overflow_event_index(3) — yes, the manual name is PAPI, and this function is giving “turn the overflow vector into an array of indexes to overflowing events” energy. no cap, let’s get into it 🫶✨

🌸 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\n  Handler(%d) Overflow at %p! vector=%#llx\n",
           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]);}
