19 PAPI_multiplex_init enables and initializes multiplex support in the
20 PAPI library. Multiplexing allows a user to count more events than
21 total physical counters by time sharing the existing counters at some
22 loss in precision. Applications that make no use of multiplexing do
23 not need to call this routine.
