I've not done this, but I think you would do
it something like this:

PRO CDFVARNAME
fID = CDF_Open(filename)
info = CDF_Inquire(fID)
nvars = info.nvars
FOR j=0,nvars-1 DO BEGIN
varInfo = CDF_VarInq(fID, j)
Help, varInfo, /Structure
Print, 'Variable Name: ', varInfo.name
ENDFOR
CDF_Close, fID
END

Cheers,

David
