You should probably reconsider it. It works only for C functions that do not expect null as a value, do not return strings allocated outside Ada, do not deallocate strings passed into. > It is a pity that I need to reimplement Indefinite_Holders for this task. Why re-implement? It has different purpose. I never used it because of its semantics. I use a different approach, maybe because it was Ada 95 when first implemented. Anyway, it works better to me. I don't like the overhead of creating messy temporary controlled helper types. -- Regards, Dmitry A. Kazakov http://www.dmitry-kazakov.de
