You can use getfsstat(..., ..., MNT_NOWAIT) to get the current list of mounted filesystems. (Note: this will include things you may not consider a "filesystem" or "volume". For example, synthetic autofs directories (/net, /home, /Network/Servers).) However, whether a remote filesystem is "accessible" or not is never certain. Even if you *just* accessed files on it, a millisecond later that server may become inaccessible. Network file systems attempt to make remote resources look like they are local. Unfortunately, networks often do not like to cooperate. HTH --macko _______________________________________________ Do not post admin requests to the list. They will be ignored.
