"The statfs() system call first appeared in 4.4BSD." (from the statfs(2) manpage on FreeBSD). struct statfs differs between Linux and BSD, but is "close enough" for this, the fields from the original patch are present in both implementations. Solaris does not have statfs() anymore. Instead, it has a statvfs() which is "more or less equivalent" to the Linux statvfs(). On FreeBSD, using statvfs() (it's available) is rather not recommended, from the man page: The statvfs() and fstatvfs() functions fill the structure pointed to by buf with garbage. This garbage will occasionally bear resemblance to file system statistics, but portable applications must not depend on this. That's funny, as statvfs() is in our beloved POSIX.1 since at least 2001 - current specs: https://pubs.opengroup.org/onlinepubs/9699919799/functions/fstatvfs.html Regards, Christoph -- Spare Space
