The comment alongside the bufferram member of struct sysinfo, as defined in the manpage above, says "Memory used by buffers". A similar meaning is given for the Buffers: line of Linux's /proc/meminfo: http://docs.redhat.com/docs/en-US/Red_Hat_Enterprise_Linux/6/html/Deployment_Guide/s2-proc-meminfo.html So IIUC, no. Yaakov
