No need to compare with zero.

In general, functions return 0 for success, and something else for an
error. So there is no need to do a comparison. Please remove all
comparisons, unless it is really needed. It also makes the code look
consistent. At the moment you sometime have < 0, sometime !=0, and
sometimes no comparison at all.
