If you have the pathname available, then you can scan the list of
mounted filesystems (using getmntent() etc), and select the closest
ancestor to the file in question. However, you would need the
canonical pathname (the one for which none of the components are
symlinks).

If you don't have the pathname, just the descriptor, then there isn't
any portable solution. There are some hacks available, but most of
them don't work for NFS mounts (for which there is no "device").

I'd suggest just including whatever information is readily available
(e.g. pathname or map name) in the error message.
