Hello,
I think I found 1 (possibly 2) bugs.
When using nf90_put_att to create a fillvalue for a long integer (8 byte) in a
netcdf4/hdf5 file, I get error message -36 NetCDF: Invalid argument.
As it turns out, the nf90 interface is not capable of writing any long
integer. I could remedy this by using the Fortran 77 interface for this
particular case. I believe the culprit is lines 211 and in
f90/netcdf_attributes.f90 (in netcdf 4.2.0, that is):
nf90_put_att_EightByteInt = nf_put_att_int(ncid, varid, name, nf90_int,
size(values), int(values))
should be
nf90_put_att_EightByteInt = nf_put_att_int(ncid, varid, name,
nf90_int64, size(values), int(values))
A similar conversion issue seems to be happening in the get_att functions
(with defaultInteger being a normal int, not a long one)
The second issue is that the fortran 77 interface could only handle 4byte
integers: Everything outside of the 4byte boundaries was converted into value
1. My guess is that the fortran interface converted the value to 4 bytes, and
that the C backend made it a long again thanks to the passing of the typeid.
Am I correct here?
Thanks,
Thijs Heus
