NAME

       PAPI_enum_event -

       Enumerate PAPI preset or native events.

SYNOPSIS

Detailed Description
       @par C Interface:
       int PAPI_enum_event( int * EventCode, int  modifer );

       Given a preset or native event code, PAPI_enum_event replaces the event
       code with the next available event in either the preset or native table.
       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 preset events, a TRUE (non-zero) value currently directs the function
       to return event codes only for PAPI preset events available on this platform.
       This may change in the future.
       For native events, the effect of the modifier argument is 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.

       @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 this platform
       *   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_event( &i, PAPI_ENUM_ALL ) == PAPI_OK );
       *

       Generic Modifiers
	   The following values are implemented for preset events

	   o PAPI_ENUM_EVENTS -- Enumerate all (default)
	   o 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

	   o PAPI_NTV_ENUM_UMASKS -- Given an event, iterate through possible umasks one at a time
	   o 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

	   o PAPI_PRESET_ENUM_AVAIL -- enumerate only available presets
	   o PAPI_PRESET_ENUM_MSC -- Miscellaneous preset events
	   o PAPI_PRESET_ENUM_INS -- Instruction related preset events
	   o PAPI_PRESET_ENUM_IDL -- Stalled or Idle preset events
	   o PAPI_PRESET_ENUM_BR -- Branch related preset events
	   o PAPI_PRESET_ENUM_CND -- Conditional preset events
	   o PAPI_PRESET_ENUM_MEM -- Memory related preset events
	   o PAPI_PRESET_ENUM_CACH -- Cache related preset events
	   o PAPI_PRESET_ENUM_L1 -- L1 cache related preset events
	   o PAPI_PRESET_ENUM_L2 -- L2 cache related preset events
	   o PAPI_PRESET_ENUM_L3 -- L3 cache related preset events
	   o PAPI_PRESET_ENUM_TLB -- Translation Lookaside Buffer events
	   o PAPI_PRESET_ENUM_FP -- Floating Point related preset events
       ITANIUM Modifiers
	   The following values are implemented for modifier on Itanium:

	   o PAPI_NTV_ENUM_IARR - Enumerate IAR (instruction address ranging) events
	   o PAPI_NTV_ENUM_DARR - Enumerate DAR (data address ranging) events
	   o PAPI_NTV_ENUM_OPCM - Enumerate OPC (opcode matching) events
	   o PAPI_NTV_ENUM_IEAR - Enumerate IEAR (instr event address register) events
	   o PAPI_NTV_ENUM_DEAR - Enumerate DEAR (data event address register) events
       POWER Modifiers
	   The following values are implemented for POWER

	   o PAPI_NTV_ENUM_GROUPS - Enumerate groups to which an event belongs
