PAPI_remove_named_event(3) PAPI PAPI_remove_named_event(3)

NAME

PAPI_remove_named_event -

removes a named hardware event from a PAPI event set.

SYNOPSIS

Detailed Description

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 papi_avail utility 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 
the current platform, run papi_native_avail in the PAPI distribution. 
@par C Interface:
int PAPI_remove_event( int  EventSet, int  EventCode );
@param[in] EventSet

-- an integer handle for a PAPI event set as created
by PAPI_create_eventset @param[in] EventName
-- a defined event such as PAPI_TOT_INS or a native event. @retval PAPI_OK
Everything worked. @retval PAPI_EINVAL
One or more of the arguments is invalid. @retval PAPI_ENOINIT
The PAPI library has not been initialized. @retval PAPI_ENOEVST
The EventSet specified does not exist. @retval PAPI_EISRUN
The EventSet is currently counting events. @retval PAPI_ECNFLCT
The underlying counter hardware can not count this
event and other events in the EventSet simultaneously. @retval PAPI_ENOEVNT
The PAPI preset is not available on the underlying hardware. @par Example:

*   char EventName = "PAPI_TOT_INS";
*   int EventSet = PAPI_NULL;
*   int ret;
*
*   // Create an empty EventSet
*   ret = PAPI_create_eventset(&EventSet);
*   if (ret != PAPI_OK) handle_error(ret);
*
*   // Add Total Instructions Executed to our EventSet
*   ret = PAPI_add_named_event(EventSet, EventName);
*   if (ret != PAPI_OK) handle_error(ret);
*
*   // Start counting
*   ret = PAPI_start(EventSet);
*   if (ret != PAPI_OK) handle_error(ret);
*
*   // Stop counting, ignore values
*   ret = PAPI_stop(EventSet, NULL);
*   if (ret != PAPI_OK) handle_error(ret);
*
*   // Remove event
*   ret = PAPI_remove_named_event(EventSet, EventName);
*   if (ret != PAPI_OK) handle_error(ret);
*
