NAME

       PAPI_list_events -

       list the events in an event set

SYNOPSIS

Detailed Description

       List the events in an event set.

       PAPI_list_events() returns an array of events and a count of the

        total number of events in an event set. This call assumes an initialized PAPI library and
       a successfully created event set.

       C Interface
           #include <papi.h>
            int PAPI_list_events(int *EventSet, int *Events, int *number );

       Parameters:
           EventSet An integer handle for a PAPI event set as created by PAPI_create_eventset
           *Events A pointer to a preallocated array of codes for events, such as PAPI_INT_INS.
           No more than *number codes will be stored into the array.
           *number On input, the size of the Events array, or maximum number of event codes to be
           returned. A value of 0 can be used to probe an event set. On output, the number of
           events actually in the event set. This value may be greater than the actually stored
           number of event codes.

       Return values:
           PAPI_EINVAL
           PAPI_ENOEVST

       Examples:

                   if (PAPI_event_name_to_code("PAPI_TOT_INS",&EventCode) != PAPI_OK)
                   exit(1);
                   if (PAPI_add_event(EventSet, EventCode) != PAPI_OK)
                   exit(1);
                   Convert a second event name to an event code
                   if (PAPI_event_name_to_code("PAPI_L1_LDM",&EventCode) != PAPI_OK)
                   exit(1);
                   if (PAPI_add_event(EventSet, EventCode) != PAPI_OK)
                   exit(1);
                   number = 0;
                   if(PAPI_list_events(EventSet, NULL, &number))
                   exit(1);
                   if(number != 2)
                   exit(1);
                   if(PAPI_list_events(EventSet, Events, &number))
                   exit(1);
