what an ordeal
unix is much easier
the function I ended with is
__declspec(dllexport) int __stdcall HOWARD(int a, int b, int c)
{
time_t t;
OPENFP;
unlink("c:/temp/howard");
LOG3("%s three values g=%d i=%d t=%d\n", a, b, c);
return 4;
}
The bad number at the beginning of the fprintf is due to a mis-copy on
my part. The fprintf function was #define'd so I could easily put
a timestamp in the code. However, that did point me to the calling
sequence and after many trials today, and many great suggestions from
the list, it is now working. I found that in addition to the calling
sequence above I also needed a *.def file and that file must be
specified to the loader. The *.def file I have is:
; charthistory.dll : accepts data from ts and then correlates the data when asked
LIBRARY "charthistory"
;DESCRIPTION: "standard windows dynamic link library"
EXPORTS
; explicit exports can go here
CCHISTCLEAR
CCHISTADDCHAIN
CCHISTADDEVENT
CCHISTSCAN
HOWARD
I hope this helps someone else!
