PAPI_get_hardware_info(3) get information about the system hardware


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.
@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)    
        if ((hwinfo = PAPI_get_hardware_info()) == NULL)
        printf("%d CPUs at %f Mhz.\n",hwinfo->totalcpus,hwinfo->mhz);
