In adding functions to my Financial project, and ran along a problem using a "..." parameter in a Windows' DLL. The function real npv( in real rRate, ... ) works fine in a .exe build, but not as a exported function in a DLL build. So I was wondering, if any one else has ran across this problem, and that maybe there's a better to do this...or is this an error in which case I should report this a an error to Walter? Many thanks in advance! :)) Below is the command-line used to compile and run the test code, there aren't any errors displaying...but the npv() function returns a zero. Also I've added all the test code (npv.d, npv.def, and loader.d) below. Command-line: Compiling and running the test code below ------------------------------------------------------- C:\dmd>bin\dmd npv.d npv.def C:\dmd\bin\..\..\dm\bin\link.exe npv,,,user32+kernel32,npv.def/noi; C:\dmd>bin\dmd loader.d C:\dmd\bin\..\..\dm\bin\link.exe loader,,,user32+kernel32/noi; C:\dmd>loader sLibName="C:\dmd\npv.dll", hLibWithDLL=268435456 "C:\dmd\npv.dll" is loaded npv's dll hex addry=10003060, Testing npv( 0.1, -10_000, 3_000, 4_200, 6_800 )= 0.00, ans=$1,188.44 sln's dll hex addry=100033AC, Testing sln( 30000, 7500, 10 )=2250.00, ans=$2,250.00 "C:\dmd\npv.dll" is unloaded C:\dmd> David L. ------------------------------------------------------------------- "Dare to reach for the Stars...Dare to Dream, Build, and Achieve!"

I would try putting a final "else" block in your function, which says, "I don't recognize the type, this is an error."

I took your suggestion and added a final else with a message, and I can clearly see that it's got the number of parameters being passed in right, but somehow the typeid() is unknown / wrong. For now I'll just use a real[] array for the DLL build, but it would've been nice to have a bit more feed back from the forum. I was really hoping for more help on this "..." parameter subject, than what can be found in the DigitalMars D html help files. ------------------------------------------------------------------- "Dare to reach for the Stars...Dare to Dream, Build, and Achieve!"In adding functions to my Financial project, and ran along a problem using a "..." parameter in a Windows' DLL.

"Real Soon Now" version 1.0 is coming out. That means Walter is (my condolences to his Family) over- worked, most of the other Gurus are busy fixing, suggesting, or creating least-lines-proofs of bugs -- not to mention that nobody has even started to ponder over updating the existing documentation to a form suitable for a Release! My bet is, 2 months after D 1.0 is out, this forum might really be the place to ask things. But definitely not before that.

Yeah, I agree with you that this is a great time with D v1.0 just around the corner to be programming in D, and that everyone here has been pretty busy. I too, feel for Walter...he's been working pretty hard these past few years on the D compiler / Phobos runtime library. Again thanks for the reply.
