gd_parent_fragment(3) GETDATA gd_parent_fragment(3)NAMEgd_parent_fragment — retrieve the parent fragment of a fragment in a
dirfile
SYNOPSIS
#include <getdata.h>
int gd_parent_fragment(DIRFILE *dirfile, int fragment_index);
DESCRIPTION
The gd_parent_fragment() function queries a dirfile(5) database speci‐
fied by dirfile and returns the index of the fragment which contains
the INCLUDE directive for the fragment indexed by fragment_index.
Since the primary format specification fragment is not included in any
other fragment, passing zero for fragment_index will result in an er‐
ror.
RETURN VALUE
On success, gd_parent_fragment() returns the index of the specified
fragment's parent. On error, gd_parent_fragment() returns -1 and sets
the dirfile error to a non-zero 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, or was equal to zero.
The dirfile error may be retrieved by calling gd_error(3). A descrip‐
tive error string for the last error encountered can be obtained from a
call to gd_error_string(3).
