Re: [xSocket-develop] Close socket after data sent

[Gregor R. <gre...@go...>]

Hi Amine,

xSocket give you 3 options to send data. By default the write operation will
be synchronous, that means the write call returns after the data is written
(into the OS-internal SO_SNDBUF). If you set the FlushMode to async, the
write method will return immediately. The write operation(s) will be done in
the background. xSocket uses an internal second-level buffer to do this. If
you have written a large amount of data and you closes the connection,
xSocket tries to flush all the data of the second-level buffer before the
connection will be closed physically. If you want to avoid large
second-level write buffer or to have more control over the flowcontrol, you
can use xSocket's IWriteCompletionHandler support. Please see chapter 25 of
the tutorial.
