12 int get_parent_fragment(const DIRFILE *dirfile, int fragment_index);
13
15 The get_parent_fragment() function queries a dirfile(5) database speci‐
16 fied by dirfile and returns the index of the fragment which contains
17 the INCLUDE directive for the fragment indexed by fragment_index.
18
19 Since the primary format file fragment is not included in any other
20 fragment, passing zero for fragment_index will result in an error.

24 On success, get_parent_fragment() returns the index of the specified
25 fragment's parent. On error, get_parent_fragment() returns -1 and sets
26 the dirfile error to a non-zero value. Possible error values are:
27
28 GD_E_BAD_DIRFILE
29 The supplied dirfile was invalid.
30
31 GD_E_BAD_INDEX
32 The supplied index was out of range, or was equal to zero.
33
34 The dirfile error may be retrieved by calling get_error(3). A descrip‐
35 tive error string for the last error encountered can be obtained from a
36 call to get_error_string(3).
