# The only portable way I can think of to see if a file is remote or not # is to check the mount table in /etc/mnttab. Although not the official # kernel version of the mount table, it does contain a flag indicating that # a file system is remote. But that would be useful only if you have a # full path name and can then traverse down the tree and remember the last # time you passed a mount point and changed file systems (according to the # mnttab). Or you could implement in user code your own version of the # kernel namei() function. Excuse me, I'm not feeling well. # Roger Noe ihnp4!att!uniq!rjnoe You can tell that you have crossed a mount point by noting that st_dev has changed, - no need for the full path - then compare your st_dev with st_rdevs for the files in /etc/mnttab to tell whether you got a remote. Not very neat, but does beat the hell out of homespun namei. Mike Cherepov
