Gd_protection report the protection level of a dirfile fragment
#include <getdata.h> int gd_protection(DIRFILE *dirfile, int fragment_index);
The gd_protection() function queries a dirfile(5) database specified by dirfile and returns the advisory protection level for the fragment indexed by fragment_index.
Upon successful completion, gd_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 gd_alter_protection(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.
GD_E_BAD_INDEX
The supplied index was out of range.
The dirfile error may be retrieved by calling gd_error(3). A descriptive error string for the last error encountered can be obtained from a call to gd_error_string(3).
