NAME

       PAPI_enum_cmp_event -

       Enumerate PAPI preset or native events for a given component.

SYNOPSIS

Detailed Description

       @par C Interface:
       int PAPI_enum_cmp_event( int *EventCode, int  modifer, int cidx );

       Given an event code, PAPI_enum_event replaces the event
       code with the next available event.

       The modifier argument affects which events are returned.
       For all platforms and event types, a value of PAPI_ENUM_ALL (zero)
       directs the function to return all possible events. @n

       For native events, the effect of the modifier argument may be
          different on each platform.
       See the discussion below for platform-specific definitions.

       @param *EventCode
           A defined preset or native event such as PAPI_TOT_INS.
       @param modifier
           Modifies the search logic. See below for full list.
           For native events, each platform behaves differently.
           See platform-specific documentation for details.

          @param cidx
                  Specifies the component to search in

       @retval PAPI_ENOEVNT
           The next requested PAPI preset or native event is not available on
           the underlying hardware.

       @par Examples:

       *   // Scan for all supported native events on the first component
       *   printf( "Name       Code   Description0 );
       *   do {
       *       retval = PAPI_get_event_info( i, &info );
       *       if ( retval == PAPI_OK ) {
       *       printf( "%-30s 0x%-10x1s0, info.symbol, info.event_code, info.long_descr );
       *       }
       *   } while ( PAPI_enum_cmp_event( &i, PAPI_ENUM_ALL, 0 ) == PAPI_OK );
       *

       Generic Modifiers
           The following values are implemented for preset events

           • PAPI_ENUM_EVENTS -- Enumerate all (default)
           • PAPI_ENUM_FIRST -- Enumerate first event (preset or native) preset/native chosen
             based on type of EventCode
       Native Modifiers
           The following values are implemented for native events

           • PAPI_NTV_ENUM_UMASKS -- Given an event, iterate through possible umasks one at a
             time
           • PAPI_NTV_ENUM_UMASK_COMBOS -- Given an event, iterate through all possible
             combinations of umasks. This is not implemented on libpfm4.
       Preset Modifiers
           The following values are implemented for preset events

           • PAPI_PRESET_ENUM_AVAIL -- enumerate only available presets
           • PAPI_PRESET_ENUM_MSC -- Miscellaneous preset events
           • PAPI_PRESET_ENUM_INS -- Instruction related preset events
           • PAPI_PRESET_ENUM_IDL -- Stalled or Idle preset events
           • PAPI_PRESET_ENUM_BR -- Branch related preset events
           • PAPI_PRESET_ENUM_CND -- Conditional preset events
           • PAPI_PRESET_ENUM_MEM -- Memory related preset events
