       PAPI_remove_event -

       removes a hardware event from a PAPI event set.


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] EventCode
          -- 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_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:

       *   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_event(EventSet, PAPI_TOT_INS);
       *   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_event(EventSet, PAPI_TOT_INS);
       *   if (ret != PAPI_OK) handle_error(ret);
