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

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.
