NAME
     getfh -- get file handle

SYNOPSIS
     #include <sys/types.h>
     #include <sys/mount.h>

     int
     getfh(const char *path, fhandle_t *fhp);

DESCRIPTION
     getfh() returns a file handle for the specified file or directory in the file handle pointed to by fhp.  This system call is restricted to
     the super-user and is used by an NFS server's nfsd(8) daemon to obtain file handles used in NFS MOUNT service replies.

RETURN VALUES
     Upon successful completion, a value of 0 is returned.  Otherwise, -1 is returned and the global variable errno is set to indicate the error.

ERRORS
     getfh() fails if one or more of the following are true:

     [ENOTDIR]		A component of the path prefix of path is not a directory.

     [ENAMETOOLONG]	The length of a component of path exceeds {NAME_MAX} characters, or the length of path exceeds {PATH_MAX} characters.

     [ENOENT]		The file referred to by path does not exist.

     [EPERM]		The caller is not the super-user.

     [EACCES]		Search permission is denied for a component of the path prefix of path.

     [ELOOP]		Too many symbolic links were encountered in translating path.

     [EFAULT]		Fhp points to an invalid address.

     [EIO]		An I/O error occurred while reading from or writing to the file system.
