get information about the system hardware More...

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.

Bug:: If called before the behavior of the routine is undefined.

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);
