Question: default fillValue for NC_VLEN types?

[krisfed]

Based on discussion here #1011 , I thought the default fill value for NC_VLEN types would be a single nc_vlen_t struct value with len=0, and p=NULL.

But when I use nc_inq_var_fill() on a freshly created NC_VLEN variable, I am seeing that by default the fill value is turned off (no_fill is 1), so then of course the returned fill value pointer is not pointing at anything useful.

I just wanted to double-check that this is behaving as expected. Let me know if this looks like a bug, and I can put together some reproduction code.

I am using 4.7.4 version.

If fill value is turned off, then what you see is correct. IF fill value is on but no
value is set, then it should use the default value.

Thank you, Dennis! But the fill value being turned off by default for NC_VLEN variables is correct?

Do not know off hand.
