hi-
On 32-bit, I can build a va_list by hand (using simple pointer arithmetic) and call functions that accept va_list.

But, on 64-bit the va_list changed and the way I build va_list on 32- bit does not work.

Are there some functions that I can uses to push variables onto the va_list (stack)? - maybe even cross-platform GNU functions?

... ANSI-C defines how to pop them off, but I can't find a good way to push them on.

thanks!-

If you want to build dynamic function call, use something like ffi which will take care of this for you.

man ffi for details.
