NAME

       PAPI_get_hardware_info - get information about the system hardware

SYNOPSIS

Detailed Description

       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.

       Return values
           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.

       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.\en",hwinfo->totalcpus,hwinfo->mhz);
