NetCDF-4 Error Codes

NetCDF-4 uses all error codes from NetCDF-3 (see section NetCDF-3 Error Codes). The following additional error codes were added for new errors unique to netCDF-4.

#define NC_EHDFERR       (-101)
#define NC_ECANTREAD     (-102)
#define NC_ECANTWRITE    (-103)

#define NC_ENOCOMPOUND   (-109)
#define NC_EATTEXISTS    (-110)
#define NC_ENOTNC4       (-111) // Attempting netcdf-4 operation on netcdf-3 file.
#define NC_ESTRICTNC3    (-112) // Attempting netcdf-4 operation on strict nc3 netcdf-4 file.
#define NC_EBADGRPID     (-113) // Bad group id. Bad!
#define NC_EBADTYPEID    (-114) // Bad type id.
#define NC_EBADFIELDID   (-115) // Bad field id.
#define NC_EUNKNAME      (-116)

DAP Error Codes
