NTV2_FILE_END Struct Reference

Data Fields
char	n_end [NTV2_NAME_LEN]
char	filler [NTV2_NAME_LEN]

Detailed Description

NTv2 binary file end record

There are files (such as all Canadian files) that have only the first four bytes correct (i.e. "END xxxx"), and there are files (such as italy/rer.gsb) that omit this record completely. Fortunately, we don't rely on the end-record when reading a file, but depend on the num-subfiles field in the overview record.

Also, very few files that I've seen actually zero out the filler field. Some files fill the field with spaces. Most files just contain garbage bytes (which is bogus, IMNSHO, since you can't then compare or checksum files properly).
