O_TRUNC will attempt to truncate the file when opened with O_RDWR
or O_WRONLY.
Normal posix open(O_RDONLY|O_TRUNC) is undefined.
libnfs nfs_open() only uses the O_TRUNC flag when used in combination with either O_RDWR or O_WRONLY.
When O_TRUNC is used together with O_RDONLY libnfs will silently ignore the O_TRUNC flag.
Libnfs nfs_open(O_RDONLY|O_TRUNC) is thus the same as nfs_open(O_RDONLY)
This is mainly needed when having to track and control the file descriptors that are used by libnfs, for example when trying to emulate dup2() ontop
of libnfs.
Add chdir and getcwd and store cwd in the nfs_context.
Add functions to process the paths specified and normalize them
by performing the transforms :
// -> /
/./ -> /
^/../ -> error
^[^/] -> error
/string/../ -> /
/$ -> \0
/.$ -> \0
^/..$ -> error
/string/..$ -> /
Update the path lookup function to allow specifying relative paths based on
cwd for all functions.

- Use _stat64 on windows so file sizes become 64bit always.
- Increase default marshalling buffer so we can marshall large PDUs.
- RPC layer support for NFSv2
- Win32 updates and fixes
- Add URL parsing functions and URL argument support.
- New utility: nfs-io
- nfs-ls enhancements
- RPC layer support for NSM
- Add example FUSE filesystem.
- Minor fixes.
We also get uid/gid for free when using READDIRPLU3 (and READDIRPLUS3 emulation)
so store these too so applications that needs to look at the uid/gid can avoid
the extra call to nfs_stat()
It only makes sense to pass url arguments to an nfs URL and thus a nfs context.
While some arguments may apply to the underlying raw rpc context (uid, gid,
tcp settings etc) some future arguments may need to apply to the nfs context
instead, such as selecting nfs version, whether or not to force sync writes
etc.
