NAME

       PAPI_add_named_event - add PAPI preset or native hardware event by name to an EventSet

SYNOPSIS

Detailed Description

       C Interface:
           #include <papi.h>
           int PAPI_add_named_event( int EventSet, const char *EventName );

       PAPI_add_named_event adds one event to a PAPI EventSet.
       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.

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

       Return values
           Positive-Integer The number of consecutive elements that succeeded before the error.
           PAPI_EINVAL One or more of the arguments is invalid.
           PAPI_ENOINIT The PAPI library has not been initialized.
           PAPI_ENOMEM Insufficient memory to complete the operation.
           PAPI_ENOEVST The event set specified does not exist.
           PAPI_EISRUN The event set is currently counting events.
           PAPI_ECNFLCT The underlying counter hardware can not count this event and other events
           in the event set simultaneously.
           PAPI_ENOEVNT The PAPI preset is not available on the underlying hardware.
           PAPI_EBUG Internal error, please send mail to the developers.
           PAPI_EMULPASS Event exists, but cannot be counted due to multiple passes required by
           hardware.

       Examples:

           char EventName = "PAPI_TOT_INS";
           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_named_event( EventSet, EventName ) != PAPI_OK )
           handle_error( 1 );
           // Add native event PM_CYC to EventSet
           if ( PAPI_add_named_event( EventSet, "PM_CYC" ) != PAPI_OK )
           handle_error( 1 );
