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_named_event( int  EventSet, const char *EventName );
@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);
*
