fhopen() opens the file referenced by
    fhp for reading and/or writing as specified by the
    argument flags and returns the file descriptor to the
    calling process. The flags are specified by
    or'ing together the flags used for the
    open(2) call. All said flags are
    valid except for O_CREAT.
fhstat(),
    fhstatvfs(), and
    fhstatvfs1() provide the functionality of the
    fstat(2),
    fstatvfs(2), and
    fstatvfs1(2) calls except
    that they return information for the file referred to by
    fhp rather than an open file.
fhopen() returns the file
  descriptor for the opened file, while fhstat(),
  fhstatvfs(), and fhstatvfs1()
  return 0. Otherwise, -1 is returned and errno is set to
  indicate the error.
fhopen(), fhstat(),
  fhstatvfs(), and fhstatvfs1()
  will return
fhopen(), and fhstat()
  functions first appeared in NetBSD 1.5. The
  fhstatvfs() function replaced
  fhstatfs() in NetBSD 3.0.
