Also, this note from MSDN documentation may
be relevant:

"The Microsoft run-time library sets the default internal
precision of the math coprocessor (or emulator) to 64 bits.
This default applies only to the internal precision at which
all intermediate calculations are performed; it does not
apply to the size of arguments, return values, or variables.
You can override this default and set the chip (or emulator)
back to 80-bit precision by linking your program with

The two cases may be working with different internal


1. Different multicast api, different result ?

Winsock has two ways of doing multicast:

The berkley socket style... and the WSA style.

The document at this link describes the two api's

I tried the berkley socket style with winsock ( UDP Multicast Test )

As some might have seen... I did NOT work that very well :)

Now I am wondering:

Is this because the network architecture does not support it ?

Or could the WSA stuff make a difference ?

UDP Speed Test and UDP Multicast Test
