Exporting DLL function with variable-argument lists

Tags: Windows, C / C++, DLL
Hello,

I'm just wondering if it is possible to have variable-argument lists on an exported DLL function i.e. a printf style function.

I would like to be able to do a logging function that may change in the future but not have to modify all of the different DLL's that use that function so exporting the one function:

int Log(char *lpszFormat, ...);

That I can then use va_start, va_end etc to get the detail out in whatever way I want.

The only question is if it is possible.

Thanks in advance.
