man dwarf_child says:
RETURN VALUES
These functions return the following values:
[DW_DLV_OK] The call succeeded.
[DW_DLV_ERROR] The requested operation failed. Additional informa-
tion about the error encountered will be recorded in
argument err, if it is not NULL.
[DW_DLV_NO_ENTRY] For functions dwarf_child() and dwarf_siblingof(), the
descriptor denoted by argument die did not have a
child or sibling. For function dwarf_offdie(), there
was no debugging information entry at the offset spec-
ified by argument offset.
However another possible value seems to be DW_DLE_NO_ENTRY.
I cannot find the definition of DW_DLE_NO_ENTRY:
find /home/dsw/elftoolchain-0.6.1 -type f -print0 | xargs -0 grep -nH DW_DLE_NO\
_ENTRY | grep define
Compilation exited abnormally with code 1 at Tue Dec 16 15:42:14
A similar search fails to find it as a value in an enum.
I am actually getting this return value, so this is a real point.
