NAME
       PAPI_remove_events -

       Remove an array of hardware event codes 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 current platform, run
       papi_native_avail in the PAPI distribution. It should be noted that PAPI_remove_events can
       partially succeed, exactly like PAPI_add_events.

       C Prototype:
	   #include <papi.h>
	    int PAPI_remove_events( int  EventSet, int * EventCode, int  number );

       Parameters:
	   EventSet an integer handle for a PAPI event set as created by PAPI_create_eventset
	   *Events an array of defined events
	   number an integer indicating the number of events in the array *EventCode

       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_ENOEVST The EventSet specified does not exist.
	   PAPI_EISRUN The EventSet is currently counting events.
	   PAPI_ECNFLCT The underlying counter hardware can not count this event and other events
	   in the EventSet simultaneously.
	   PAPI_ENOEVNT The PAPI preset is not available on the underlying hardware.

       Example:

	   int EventSet = PAPI_NULL;
	   int Events[] = {PAPI_TOT_INS, PAPI_FP_OPS};
	   int ret;

	    // Create an empty EventSet
	   ret = PAPI_create_eventset(&EventSet);
	   if (ret != PAPI_OK) handle_error(ret);

	   // Add two events to our EventSet
	   ret = PAPI_add_events(EventSet, Events, 2);
	   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_events(EventSet, Events, 2);
	   if (ret != PAPI_OK) handle_error(ret);
