PAPI_add_named_event Class Reference

add PAPI preset or native hardware event by name to an EventSet More...

Detailed Description

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

PAPI_add_named_event adds one event to a PAPI EventSet. @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.

@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_ENOINIT 
    The PAPI library has not been initialized.
@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:
* 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 );
*
Bug:
The vector function should take a pointer to a length argument so a proper return value can be set upon partial success.
