Upon successful completion, get_protection() returns the advisory protection level of the specified fragment, which will be one of the following symbols.

GD_PROTECT_NONE,~GD_PROTECT_FORMAT,~GD_PROTECT_DATA,~ GD_PROTECT_ALL. The meaning of these symbols are explained in the dirfile_protect(3) man page. On error, it returns -1 and sets the dirfile error to a non-zero error value. Possible error values are:

GD_E_BAD_DIRFILE

The supplied dirfile was invalid.
