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  a negative-valued error code.  Possible error codes
       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 error code is also stored in the DIRFILE  object  and  may  be  retrieved  after  this
       function  returns by calling gd_error(3).  A descriptive error string for the error may be
       obtained by calling gd_error_string(3).

HISTORY

       The get_parent_fragment() function appeared in GetData-0.5.0.

       In GetData-0.7.0, this function was renamed to gd_parent_fragment().

       In GetData-0.10.0, the error return from this function changed  from  -1  to  a  negative-
       valued error code.
