[ncl-talk] file format inquiry

Hi,

I have an NCL script that does some generic file processing. It reads in
a collection of files, does some math, and generates an output file. All
files are NetCDF. If the input files use 64 bit offsets, then the output
file will need to as well.

Is there a way in NCL to check to see if the input files use 64 bit
offsets? I don't see it from looking at the list of I/O functions. I
could imagine this inquiry coming from a hypothetical function called
getfileoption, which would be to setfileoption as ListGetType is to
ListSetType.

I imagine I could use the system command, and check the first line of
ncdump -h to determine this, but this seems kinda clumsy, when the C
interface to NetCDF, which NCL presumably has under the covers, provides
this functionality via the nc_inq_format function.

Thanks, Keith
