PAPI_get_hardware_info3
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.
Return values
PAPI_EINVAL One or more of the arguments is invalid.

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);
