sorry for chime in late.
I don't think /Oicf is supported in original 95, but it's supported in Win98
etc. After the original Windows 95, RPC in following Win9x family is
basically in sync with NT4sp4 and beyond. /Oicf support is added that time.
However, no /robust support is available in Win9x and NT4 family though. can
you give me a pointer to the document where we say /Oicf is not supported in
Win98? We might need to follow up with documentation.
Also, is the following what you really want?
Call([out] long *pSize, [out,size_is(,*pSize)] Test1 **pptr)
Please noticed that I don't have a "1" in front of the comma. In this case,
pptr is not a multi-dimensional array. It is a pointer to a variable
sized-array whose size is *pSize.
In your definition, ptr becomes a multi-dimensional array, whose first
dimension is a fixed size 1 array, and second dimension is variable sized
array.
Please let me know if this clarify things a bit.
thanks,
Yong
