Tcp Socket Buffer Size is a Suggestion

[Aidan63]

On Windows if I set the send and receive buffers of a TCP socket to something like 7000 and then fetch the value it comes out as 7000, but on linux fetching the value returns 16384. I'm guessing these buffer sizes are more of a suggestion to the OS and its free to choose a different value. So, should our API recognise this? Might be be better to have these functions return the value which was set, similar to how write functions return how many bytes were actually sent vs what you offered.
