'size' may be 0 to test if the call would succeed. 'buffer' is the return buffer and must be at least 'size' bytes. NB. The remote driver imposes a 64K byte limit on 'size'. For your program to be able to work reliably over a remote connection you should split large requests to <= 65536 bytes.]]> attribute within //domain/devices/disk. (For example, "xvda"). Domains may have more than one block device. To get stats for each you should make multiple calls to this function. Individual fields within the stats structure may be returned as -1, which indicates that the hypervisor does not support that particular statistic.]]>
