PAPI_get_hardware_info -

get information about the system hardware

In C, this function returns a pointer to a structure containing information about the hardware on which the program runs. 

In Fortran, the values of the structure are returned explicitly. @retval PAPI_EINVAL
One or more of the arguments is invalid.

@note The C structure contains detailed information about cache and TLB sizes. 

This information is not available from Fortran. @par Examples:


const PAPI_hw_info_t *hwinfo = NULL;
if (PAPI_library_init(PAPI_VER_CURRENT) != PAPI_VER_CURRENT)
exit(1);
if ((hwinfo = PAPI_get_hardware_info()) == NULL)
exit(1);
printf("%d CPUs at %f Mhz.\n",hwinfo->totalcpus,hwinfo->mhz); *
