For meaningful measurements, the 45increment in block count during a specific time interval should be 46calculated. For this command, read-only access to the device is 47sufficient. 48 49 50Return Value 51============ 52 53On success 0 is returned. 54 55On error -1 is returned, and the ``errno`` variable is set 56appropriately. 57 58Generic error codes are described at the 59:ref:`Generic Error Codes <gen-errors>` chapter. 60
