DESCRIPTION
Function dwarf_die_link() links debugging information entries together.
Argument die should specify the debugging information entry to be
updated.

information entry.

information entry.
Argument left specifies the new left sibling link for the debugging
information entry.
Argument right specifies the new right sibling link for the debugging
information entry.
Only one of arguments parent, child, left and right is allowed to be non-

information entries, if any, will be unlinked before the specified link
is established.
If argument err is not NULL, it will be used to store error information
in case of an error.
RETURN VALUES
On success, function dwarf_die_link() returns the debugging information
entry provided in argument die. In case of an error, function
dwarf_die_link() returns DW_DLV_BADADDR and sets the argument err.
ERRORS
The function dwarf_die_link() can fail with:
[DW_DLE_ARGUMENT] Argument die was NULL.
[DW_DLE_ARGUMENT] More than one of the arguments parent, child, left
and right were non-NULL.
