gd_parent_fragment(3) GETDATA gd_parent_fragment(3)
NAME
gd_parent_fragment -- retrieve the parent fragment of a fragment in a dirfile
SYNOPSIS
#include <getdata.h>
int gd_parent_fragment(const DIRFILE *dirfile, int fragment_index);
DESCRIPTION
The gd_parent_fragment() function queries a dirfile(5) database specified 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
error.
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 descriptive error string for the last error encountered can be obtained from
a call to gd_error_string(3).
