Hi Ed,
Yup, you are correct - I'll report it as a doc bug.

Greeting to HDF HQ!
Some questions:
1 - If any dimension of a dataset is to be extensible, the dataset
must be chunked, correct?
2 - If I have a dataset with one expendables dimension, and several
fixed dimensions, I can create it using a space like this:
if ((spaceid = H5Screate_simple(var->ndims, dimsize, maxdimsize)) < 0)
BAIL(NC_EHDFERR);
Where dimsize is an array of initial dimension sizes, and maxdimsize
is an array of max dimension sizes, or -1 for an unlimited dimension.
The problem I have is this. If I try and create a space with one of
the dimsizes as zero, and the corresponding maxdimsize as -1, HDF5
hands when I try to close the defined dataset (this seems like a HDF
bug, BTW).
So I can do it if I start with a dimsize of 1 instead of 0, but this
is not the netcdf way. After defining such a dataset, when I get the
number of records in it, using H5Sget_simple_extent_dims, I get a size
of one along that dimension, even though I haven't written any data to
it yet, because I have to define it as having length of at least one.
Any comment or help would be appreciated...
Thanks!
Ed
