This is a very simple experiment to test how uv_wait will behave before going to sleep. I’m using uv_wait on node 0, and then I’ll use another test socket to send data from socket 1 to socket 2. This simple experiment gives you a nice picture of how uv_wait works.
uv_wait is an experimental driver for the uv_tcp library. The uv_tcp library is a smallish library which implements the low-level functionality of the uv_poll system call. uv_tcp is a generic driver for uv_tcp_recv() and uv_tcp_send() which will be used by the uv_loopback system call.
uv_wait is designed to be used for the time spent in an event loop, where we want to wait for an event to happen. uv_wait is just a wrapper for the uv_tcp_recv and uv_tcp_send calls. uv_wait will wait for the event or socket to be closed by the kernel before going to sleep.
The uv_poll library does not work in the standard linux/unix/linux/lib/udp/udc/udc.hpp, which is really a compiler-block that implements uv_poll.
uv_poll will be removed to be replaced by uv_loopback (which will be removed to be replaced by uv_loop).
uv_wait is a wrapper for uv_poll and uv_loopback, but uv_wait is not the same thing as uv_tcp_recv (which is a wrapper for uv_recv). It’s supposed to be a wrapper function that takes a callback called uv_wait and returns false if uv_wait is not called or returned before uv_poll is called.
I see the same thing happening when you are on your own internet that you don’t know about, and uv_run is what’s supposed to be a wrapper for uv_loopback. It’s supposed to be a wrapper function called wait, and it takes a callback called wait and returns false if uv_loopback is not called. It’s still uv_poll, uv_tcp_recv, and uv_poll itself.
It’s not meant to be a wrapper function, because its supposed to be a wrapper function. Its supposed to be a function that takes nothing but uv_poll and returns uv_tcp_recv in a callback called wait, and it is supposed to be a function that takes nothing but uv_poll and returns uv_poll in a callback called wait.
The uv_loopback flag is what makes uv_tcp_recv and uv_poll differ. uv_poll is a function that is called by the kernel when a connection is ready to be accepted by the kernel but not yet ready to be used by the kernel.
uv_loopback is a flag that tells the kernel that it has successfully accepted a connection. It is used by the kernel to decide whether it should loop back to the socket or not. It is also how the kernel is able to decide if a connection is ready to be used by it.
