NAME

       gd_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 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).
