I don't see the reason for the "i>1" condition, but you are correct in
excluding the unlimited dimension. Here is what my fix looks like:
if ((t[i] >= get_dim(i)->size()) &&
!get_dim(i)->is_unlimited())
return FALSE; // too big for dimension
and the same fix is needed a little further down, in the other version of
set_cur()
if ((cur[i] >= get_dim(i)->size()) &&
!get_dim(i)->is_unlimited())
return FALSE;
I've been meaning to put together another patch with this and additional
fixes to the C++ interface, but I haven't found the necessary time yet. I
assume you've already applied the set of C++ patches in
ftp://ftp.unidata.ucar.edu/pub/netcdf/2.3.2-patch3
to the current distribution. I've appended the current diffs between that
and what bug fixes I have accumulated, but I'm afraid I can't gaurantee much
except that this passes the simple test I constructed with "make test" in
the C++ directory.
