How to check if a file is indeed a NetCDF file? [message #15034]

Hello,

In trying to read NetCDF data files in IDL, I've discovered that the
NCDF_OPEN crashes on me if the file I ask it to open is not a nCDF file.
It crashes somewhat gracefully in that it tells me that NCDF_OPEN
couldn't open the file and the error # is 19. Does anyone out there know
how to use the IDL NCDF library to determine whether or not a file is in
NetCDF format? The fact that the most obvious solution (i.e. NCDF_OPEN
*returns* an error # rather than falling in a heap) doesn't work like I
would expect doesn't make me too hopeful.

Any info appreciated.
