NAME

       PAPI_is_initialized -

       check for initialization

SYNOPSIS

Detailed Description
       @retval PAPI_NOT_INITED
	   Library has not been initialized
       @retval PAPI_LOW_LEVEL_INITED
	   Low level has called library init
       @retval PAPI_HIGH_LEVEL_INITED
	   High level has called library init
       @retval PAPI_THREAD_LEVEL_INITED
	   Threads have been inited

       @param version
	upon initialization, PAPI checks the argument against the internal value of PAPI_VER_CURRENT when the library was compiled.
       This guards against portability problems when updating the PAPI shared libraries on your system.
       @par Examples:

	       int retval;
	       retval = PAPI_library_init(PAPI_VER_CURRENT);
	       if (retval != PAPI_VER_CURRENT && retval > 0) {
	       fprintf(stderr,"PAPI library version mismatch!
");
	       exit(1); }
	       if (retval < 0)
	       handle_error(retval);
	       retval = PAPI_is_initialized();
	       if (retval != PAPI_LOW_LEVEL_INITED)
	       handle_error(retval);
       *

	PAPI_is_initialized() returns the status of the PAPI library. The PAPI library can be in one of four states, as described under RETURN
       VALUES.

NAME

       PAPI_event_name_to_code -

       Convert a name to a numeric hardware event code.

SYNOPSIS

Detailed Description
       @par C Interface:
       int PAPI_event_name_to_code( char * EventName, int * EventCode );

       PAPI_event_name_to_code is used to translate an ASCII PAPI event name
       into an integer PAPI event code.

       @param *EventCode
	   The numeric code for the event.
       @param *EventName
	   A string containing the event name as listed in PAPI_presets or discussed in PAPI_native.

       @retval PAPI_EINVAL
	   One or more of the arguments is invalid.
       @retval PAPI_ENOTPRESET
	   The hardware event specified is not a valid PAPI preset.
       @retval PAPI_ENOINIT
	   The PAPI library has not been initialized.
       @retval PAPI_ENOEVNT
	   The hardware event is not available on the underlying hardware.

       @par Examples:

       *   int EventCode, EventSet = PAPI_NULL;
       *   // Convert to integer
       *   if ( PAPI_event_name_to_code( "PAPI_TOT_INS", &EventCode ) != PAPI_OK )
       *   handle_error( 1 );
       *   // Create the EventSet
       *   if ( PAPI_create_eventset( &EventSet ) != PAPI_OK )
       *   handle_error( 1 );
       *   // Add Total Instructions Executed to our EventSet
       *   if ( PAPI_add_event( EventSet, EventCode ) != PAPI_OK )
       *   handle_error( 1 );
       *
