To get the text explanation of an error return code, you can print the
string returned from the documented function nc_strerror(), as in:
std::cout << "status: " << status << " means\n" <<
nc_strerror(status) << "\n" ;
which will output
status: -39 means
Operation not allowed in define mode
The meaning of the error is that the file is already in define mode
(since it was just created with a call to nc_create()), so you cannot
call nc_redef() to put it in define mode.
Also as a reminder, usage questions about netCDF should generally be
sent to support@xxxxxxxxxxxxxxxx rather than the netcdfgroup mailing
list, which is intended for announcements and discussion.
