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).
