in is for input parameter (the called C procedure get a value from the VHDL caller) out is for output parameter (the called C procedure returns a value to the VHDL caller) For your signal problem: you can't have a signal as an output variable parameter "out", it is possible with a "in" _______________________________________________ Ghdl-discuss mailing list [email protected] https://mail.gna.org/listinfo/ghdl-discuss
