NAME

       PAPI_event_name_to_code -

       Convert a name to a numeric hardware event code.

SYNOPSIS

Detailed Description
       @par C Interface:
       int PAPI_event_name_to_code( char * EventName, int * EventCode );

       PAPI_event_name_to_code is used to translate an ASCII PAPI event name
       into an integer PAPI event code.

       @param *EventCode
	   The numeric code for the event.
       @param *EventName
	   A string containing the event name as listed in PAPI_presets or discussed in PAPI_native.

       @retval PAPI_EINVAL
	   One or more of the arguments is invalid.
       @retval PAPI_ENOTPRESET
	   The hardware event specified is not a valid PAPI preset.
       @retval PAPI_ENOINIT
	   The PAPI library has not been initialized.
       @retval PAPI_ENOEVNT
	   The hardware event is not available on the underlying hardware.

       @par Examples:

       *   int EventCode, EventSet = PAPI_NULL;
       *   // Convert to integer
       *   if ( PAPI_event_name_to_code( "PAPI_TOT_INS", &EventCode ) != PAPI_OK )
       *   handle_error( 1 );
       *   // Create the EventSet
       *   if ( PAPI_create_eventset( &EventSet ) != PAPI_OK )
       *   handle_error( 1 );
       *   // Add Total Instructions Executed to our EventSet
       *   if ( PAPI_add_event( EventSet, EventCode ) != PAPI_OK )
       *   handle_error( 1 );
       *

NAME

       PAPI_add_event -

       add PAPI preset or native hardware event to an event set

SYNOPSIS

Detailed Description
       @par C Interface:
       int PAPI_add_event( int	EventSet, int  EventCode );

       PAPI_add_event adds one event to a PAPI Event Set. @n
       A hardware event can be either a PAPI preset or a native hardware event code.
       For a list of PAPI preset events, see PAPI_presets or run the avail test case
       in the PAPI distribution. PAPI presets can be passed to PAPI_query_event to see
       if they exist on the underlying architecture.
       For a list of native events available on current platform, run the papi_native_avail
       utility in the PAPI distribution. For the encoding of native events,
       see PAPI_event_name_to_code to learn how to generate native code for the
       supported native event on the underlying architecture.

       @param EventSet
	   An integer handle for a PAPI Event Set as created by PAPI_create_eventset.
       @param EventCode
	   A defined event such as PAPI_TOT_INS.

       @retval Positive-Integer
	   The number of consecutive elements that succeeded before the error.
       @retval PAPI_EINVAL
	   One or more of the arguments is invalid.
       @retval PAPI_ENOMEM
	   Insufficient memory to complete the operation.
       @retval PAPI_ENOEVST
	   The event set specified does not exist.
       @retval PAPI_EISRUN
	   The event set is currently counting events.
       @retval PAPI_ECNFLCT
	   The underlying counter hardware can not count this event and other events
	   in the event set simultaneously.
       @retval PAPI_ENOEVNT
	   The PAPI preset is not available on the underlying hardware.
       @retval PAPI_EBUG
	   Internal error, please send mail to the developers.

       @par Examples:

       *   int EventSet = PAPI_NULL;
       *   unsigned int native = 0x0;
       *   if ( PAPI_create_eventset( &EventSet ) != PAPI_OK )
       *   handle_error( 1 );
       *   // Add Total Instructions Executed to our EventSet
       *   if ( PAPI_add_event( EventSet, PAPI_TOT_INS ) != PAPI_OK )
       *   handle_error( 1 );
       *   // Add native event PM_CYC to EventSet
       *   if ( PAPI_event_name_to_code( "PM_CYC", &native ) != PAPI_OK )
       *   handle_error( 1 );
       *   if ( PAPI_add_event( EventSet, native ) != PAPI_OK )
       *   handle_error( 1 );
       *
