NAME

       PAPI_get_component_info -

       get information about a specific software component

SYNOPSIS

Detailed Description
       @param cidx
	   Component index

       This function returns a pointer to a structure containing detailed
       information about a specific software component in the PAPI library.
       This includes versioning information, preset and native event
       information, and more.
       For full details, see @ref PAPI_component_info_t.

       @par Examples:

	       const PAPI_component_info_t *cmpinfo = NULL;
	       if (PAPI_library_init(PAPI_VER_CURRENT) != PAPI_VER_CURRENT)
	       exit(1);
	       if ((cmpinfo = PAPI_get_component_info(0)) == NULL)
	       exit(1);
	       printf("This component supports %d Preset Events and %d Native events.0,
	   cmpinfo->num_preset_events, cmpinfo->num_native_events);
       *

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.
