[netcdfgroup] What does nc_open returning 24 mean?

[Dave Allured]

All,

According to the docs for the Netcdf C interface, Nate's error code 
for too many files open should be -34, not 24.  24 is not listed.

http://www.unidata.ucar.edu/software/netcdf/docs/netcdf-c/Error-Codes.html

Does anyone know the reason for this discrepancy?  I ask for 
reference only.  Thanks.
