Hello,
Are there missing error codes in the netcdf_constants.f90 module in v4.2 of the
Fortran90 netcdf library?
I'm using the "find a group by name" inquiry function, NF90_INQ_GRP_NCID(). The
documentation states the following return codes may be returned by this
function:
NF90_NOERR - No error.
NF90_EBADID - Bad group id.
NF90_EINVAL - No name provided or name longer than NF90 MAX NAME.
NF90_ENOGRP - Named group not found.
NF90_ENOTNC4 - Attempting a netCDF-4 operation on a netCDF-3 file. NetCDF-4
operations can only be performed on files defined with a create mode which
includes flag HDF5. (see Section 2.6 [NF90 OPEN], page 11).
NF90_ESTRICTNC3 - This file was created with the strict netcdf-3 flag,
therefore netcdf-4 operations are not allowed. (see Section 2.6 [NF90 OPEN],
page 11).
NF90_EHDFERR - An error was reported by the HDF5 layer.
But when I test for "NF90_ENOGRP" I get a compilation error:
CASE (NF90_ENOGRP)
1
Error: Symbol 'nf90_enogrp' at (1) has no IMPLICIT type
And when I check the "netcdf_constants.f90" source I see ONLY the following
error codes defined:

! error codes:
!
integer, parameter, public :: &
nf90_noerr = 0, &
nf90_ebadid = -33, &
nf90_eexist = -35, &
nf90_einval = -36, &
nf90_eperm = -37, &
nf90_enotindefine = -38, &
nf90_eindefine = -39, &
nf90_einvalcoords = -40, &
nf90_emaxdims = -41, &
nf90_enameinuse = -42, &
nf90_enotatt = -43, &
nf90_emaxatts = -44, &
nf90_ebadtype = -45, &
nf90_ebaddim = -46, &

nf90_emaxvars = -48, &
nf90_enotvar = -49, &
nf90_eglobal = -50, &
nf90_enotnc = -51, &
nf90_ests = -52, &
nf90_emaxname = -53, &
nf90_eunlimit = -54, &
nf90_enorecvars = -55, &
nf90_echar = -56, &
nf90_eedge = -57, &
nf90_estride = -58, &
nf90_ebadname = -59, &
nf90_erange = -60, &
nf90_enomem = -61, &
nf90_evarsize = -62, &
nf90_edimsize = -63, &
nf90_etrunc = -64
So where did the documented error code go?
grep-ing the C source I see that nc3dispatch.c has:
#ifndef NC_ENOGRP
#define NC_ENOGRP (-125)
#endif
When I define the above value in my own module, e.g.
integer, parameter :: nf90_enogrp = -125
the code compiles, and when I run my unit tests printing out the inquiry
function result for a missing group,
nf90_stat = NF90_INQ_GRP_NCID(groupid, 'accoeff', embedid)
print *, 'ACCoeff group id inquire result: ',nf90_stat
I get what I sort of expected:
UnitTest_Setup: netCDF Write/Read Test; CALLER: Test_SpcCoeff
ACCoeff group id inquire result: -125
ACCoeff group id inquire result: -125
ACCoeff group id inquire result: -125
UnitTest_Report:
Passed 3 of 3 tests
Failed 0 of 3 tests
Timing_Display(INFORMATION) : Elapsed time-- 00:00:00.086
So is this missing error code a bug in the fortran90 API?
Or is the code somewhere else and I didn't build the library properly? I've
been using the netCDF4 libraries, via the f90 API, for several weeks no with no
other issues.
I also notice there are other codes missing from the list in
netcdf_constants.f90 that are listed in the Fortran90 documentation.
Thanks for any info.
cheers,
