__fstatfs

["Pisupati, Ajay" <ajay.pisupati@pw.utc.com>]

Ethan,
	there is a glibc function __fstatfs which basically takes in a path
and returns among other things, the type of FS that the file is on.  I am
sure you are aware of it.  I tried today to find the source for this
function and I really could not.  this could be due my ignorance, don't
really know.  but, do you know this function? if so, can you point me to
where it is implemented? basically I ended up concluding that it is a system
call.  can you confirm this? 
Thanks,
ajay
BTW, what time are you available on IRC?
