Transport protocols and bulk file transfer

[Lisong Xu <>]

Steve, Thanks for your work. I have a few quick questions about the API.

1) About x_sockstats(X_SOCKET skt)
Why for a SOCK_STREAM, it does not return buffer occupancy?
Also can this function return more information? For example, the number 
of lost packets, the number of re-transmissited packets, the number of 
loss events, ....

2) About x_send(X_SOCKET skt, const void *buf, int len)
If skt is of type SOCK_DGRAM, then the data is sent as a single message. 
Is there a maximum limit for the UDP message size? What happens, if 
"len" is greater than that limit?

Thanks
Lisong
