The form of argument .Ar attr must be .Dv DW_FORM_ref_sig8 .
p If argument .Ar err is not NULL, it will be used to return an error descriptor in case of an error. .Sh RETURN VALUES Function .Fn dwarf_formsig8 returns .Dv DW_DLV_OK on success. In case of an error, it returns .Dv DW_DLV_ERROR and sets argument .Ar err . .Sh ERRORS Function .Fn dwarf_formsig8 may fail with the following errors: l -tag -width ".Bq Er DW_DLE_ATTR_FORM_BAD" t Bq Er DW_DLE_ARGUMENT Either of arguments .Ar attr or .Ar ret was NULL. t Bq Er DW_DLE_ATTR_FORM_BAD The attribute referenced by argument .Ar attr was not of a permitted kind. .El .Sh SEE ALSO .Xr dwarf 3 , .Xr dwarf_attr 3 , .Xr dwarf_formflag 3 , .Xr dwarf_formref 3 , .Xr dwarf_formsdata 3 , .Xr dwarf_formstring 3 , .Xr dwarf_formudata 3 , .Xr dwarf_hasattr 3 .Sh HISTORY Type signatures were added in version 4 of the DWARF specification.
