p Argument .Ar ret_off should point to a location that is to hold the returned section-relative offset. If argument .Ar err is non-NULL, it is used to return an error descriptor in case of an error. .Sh RETURN VALUES On success, function .Fn dwarf_attroffset returns .Dv DW_DLV_OK .
p In case of an error, it returns .Dv DW_DLV_ERROR and sets argument .Ar err . .Sh COMPATIBILITY This function is an extension to the .Xr DWARF 3 API. .Sh ERRORS The .Fn dwarf_attroffset function may fail with the following errors: l -tag -width ".Bq Er DW_DLE_ARGUMENT" t Bq Er DW_DLE_ARGUMENT Either of the arguments .Ar at or .Ar ret_off was NULL. .El .Sh SEE ALSO .Xr dwarf 3 , .Xr dwarf_attr 3
