       PAPI_state -

       Return the counting state of an EventSet.

Detailed Description
       C Interface:
	   #include <papi.h>
	    int PAPI_state( int  EventSet, int * status );

	   EventSet -- an integer handle for a PAPI event set as created by PAPI_create_eventset
	   status -- an integer containing a boolean combination of one or more of the following
	   nonzero constants as defined in the PAPI header file papi.h:

	   o PAPI_STOPPED -- EventSet is stopped
	   o PAPI_RUNNING -- EventSet is running
	   o PAPI_PAUSED -- EventSet temporarily disabled by the library
	   o PAPI_NOT_INIT -- EventSet defined, but not initialized
	   o PAPI_OVERFLOWING -- EventSet has overflowing enabled
	   o PAPI_PROFILING -- EventSet has profiling enabled
	   o PAPI_MULTIPLEXING -- EventSet has multiplexing enabled
	   o PAPI_ACCUMULATING -- reserved for future use
	   o PAPI_HWPROFILING -- reserved for future use

       Return values:
	   PAPI_EINVAL One or more of the arguments is invalid.
	   PAPI_ENOEVST The EventSet specified does not exist.

       PAPI_state() returns the counting state of the specified event set.
