I'm curious to know if, after a WebSocket has been established (after having received the proper handshake from a server that supports them), whether or not the TCP socket used by the "WebSocket connection" is used exclusively by the WebSocket, or if the browser may still make regular HTTP requests…

My program uses sockets, what Parallel computing APIs could I use that would help me without obligating me to go from sockets to anything else?
When we are on a cluster with a special, non-socket infrastructure system this API would emulate something like sockets but using that infrastructure (so…

I'd like to know if there's a way to get the number of seconds since the UNIX epoch in any POSIX compliant shell, without resorting to non-POSIX languages like perl, or using non-POSIX extensions like GNU awk's strftime function.
Here are some solutions I've already ruled out...

In a linux application I'm using pipes to pass information between threads.
The idea behind using pipes is that I can wait for multiple pipes at once using poll(2). That works well in practice, and my threads are sleeping most of the time and only wake up if there is something to do for them.

Hi
Do you know about any good library wrapping posix and linux functions and structures ( eg. sockets or file descriptors ) into C++ classes? For example I'm thinking about a base FileDescriptor class and some inheriting classes ( unix sockets etc ) with methods like write, read or even some syscalls…
