How to fetch NFS mount options programmatically

[Corinna Vinschen]

Hi,

When I open files and directories on an NFS share, I'd like to know
beforehand, whether the filesystem has been mounted with the NFS
casesensitive mount option set to yes or no. Unfortunately, the
NtQueryVolumeInformationFile(FileFsAttributeInformation) always returns
the flag FILE_CASE_SENSITIVE_SEARCH set to FALSE, even if the filesystem
has been mounted with -o casesensitive=yes, and even if the kernel
obcaseinsensitive flag is set to 0.

So the question is, is there some API to fetch the actual mount options
when opening a handle to the filesystem? Maybe even a documented API?

Thanks in advance,
Corinna
