Hello, I do not see any obvious issues with what you have written; let me take a look at the C++ interface and see if I can figure out what is going on. I will follow up with you after I have some additional information. -Ward > Good afternoon, > > I feel I am very close to implementing a functional c++ program to extract a > chunk of NetCDF data from the HYCOM/GOFS 3.1 Hindcast data. > [http://tds.hycom.org/thredds/dodsC/GLBv0.08/expt_93.0.html > <http://tds.hycom.org/thredds/dodsC/GLBv0.08/expt_93.0.html>] > > However, when I attempt to pass an array (of type float, or double, say) by > reference to getVar(), the temperature and salinity values are not being > written to the array. > > I believe I have sized/pre-allocated the array correctly, and am using the > startp and countp vectors correctly; I do not know what is going wrong.
