p Argument .Ar die should specify the debugging information entry to be updated.
p Argument .Ar parent specifies the new parent link for the debugging information entry.
p Argument .Ar child specifies the new first child link for the debugging information entry.
p Argument .Ar left specifies the new left sibling link for the debugging information entry.
p Argument .Ar right specifies the new right sibling link for the debugging information entry.
p Only one of arguments .Ar parent , .Ar child , .Ar left and .Ar right is allowed to be non-NULL. Existing links to parent, child, left or right debugging information entries, if any, will be unlinked before the specified link is established.
p If argument .Ar err is not NULL, it will be used to store error information in case of an error. .Sh RETURN VALUES On success, function .Fn dwarf_die_link returns the debugging information entry provided in argument .Ar die . In case of an error, function .Fn dwarf_die_link returns .Dv DW_DLV_BADADDR and sets the argument .Ar err . .Sh ERRORS The function .Fn dwarf_die_link can fail with: l -tag -width ".Bq Er DW_DLE_ARGUMENT" t Bq Er DW_DLE_ARGUMENT Argument .Ar die was NULL. t Bq Er DW_DLE_ARGUMENT More than one of the arguments .Ar parent , .Ar child , .Ar left and .Ar right were non-NULL. .El .Sh SEE ALSO .Xr dwarf 3 , .Xr dwarf_add_die_to_debug 3 , .Xr dwarf_new_die 3
