So, yes you have to use htonf, etc :)
I don't have a solution at hand, still I'd like to point to a place in FlightGear where this stuff "simply works": The current multiplayer network interface allows to set IRIX/N32 against Linux/AMD64 and they both communicate nicely to each other. This setup includes different word-size, different byte order and different compiler. The guys who have designed this interface definitely did an excellent job, Martin. -- Unix _IS_ user friendly - it's just selective about who its friends are ! -------------------------------------------------------------------------- ------------------------------------------------------------------------- Take Surveys.
