Yes, and it's in the netCDF User's Guide as well, though perhaps not where
one would expect to find it.  In section 4.3, "Reading a netCDF File with
Unknown Names":

     Dimension IDs are assigned by using consecutive integers (beginning
  at 0 in C, 1 in FORTRAN).  Also dimensions, once created, cannot be
  deleted.  Therefore, knowing the number of dimension IDs in a netCDF
  means knowing all the dimension IDs: they are the integers 0, 1, 2,
  ..., (or 1, 2, 3, ... in FORTRAN).  For each dimension ID, a call to
  the inquire function `ncdiminq' (or `NCDINQ') returns the dimension
  name and size.
