kqueue | BSD file system notifications for Go | Notification library

This is my code:

I have an implemented interface based IO Completion Ports Windows - I want to try and use it together with libcurl.

The online book curl says that:

There are numerous event based systems to select from out there, and libcurl is completely agnostic to which one you use. libevent, libev and libuv are three popular ones but you can also go directly to your operating system's native solutions such as epoll, kqueue, /dev/poll, pollset, Event Completion or I/O Completion Ports.

I am reading online Curl book chapter on multi socket: "multi_socket" interface

It says:

libcurl informs the application about socket activity to wait for with a callback called CURLMOPT_SOCKETFUNCTION. Your application needs to implement such a function:

Using this, libcurl will set and remove sockets your application should monitor. Your application tells the underlying event-based system to wait for the sockets. This callback will be called multiple times if there are multiple sockets to wait for, and it will be called again when the status changes and perhaps you should switch from waiting for a writable socket to instead wait for it to become readable.

The devil himself can't figure out how it works.

-For example:

-Created completion port: CreateIoCompletionPort ()

-Created completion port handler: GetQueuedCompletionStatus ()

-Created a windows asynchronous socket: WSASocket ()

-filled in all the necessary structures like - sockadrr

-Connected to remote server: WSAConnect ()

-Linked socket to the IO Completion Port.

-Called the WSASend () and send to server message.

-Now I want libcurl to read the message from the server and do all the necessary actions, but I absolutely cannot understand from the description how ???

libcurl informs the application about socket activity to wait for with a callback called CURLMOPT_SOCKETFUNCTION.

How is this call -back function called? Who will call her? Where ? why and why ?? I do not understand (((((

Please, help :(

I was building apps with xamarin.forms before for a while, and of today: the first time my app connects to our API the app halts on no specific line stating:

How to read the request body in reactor-netty server? I want to get the request body to determine the content of the response, but I can't find an example of that in the sample code.

It seems that Ktor WebSocket cannot support Android Turkish locale. The below code is work well other than Turkish locale. It crash when I change device locale to Turkish (I checked 28 locale ​​including Arabic) Even if I test it on various devices(SS smart phone, Custom device based on AOSP8), but it does not work with only have difference crash location.

Could you please let me know how to do it?

I'm a frontend developer so my knowledge of Java, Spring and IntelliJ is virtually zero.

I accidentally deleted my company's repo on my local machine so I re-cloned it back from GitHub. I was unable to click the "debug" button as it was grayed out so I asked a colleague what their Run/Debug configurations were and added it to my editor.

Normally, I would click on "debug" and it would run and work with the frontend, but now when I run it this is the error I receive:

I have a small Ktor app (I know it's a stupid app, I am a beginner trying to learn Ktor):

I want to "transform" the below form-data request in postman into java code (within a java caller). More precisely, I`m trying to implement a caller to the below displayed api so i can access the endpoint through a jar. The problem is that I have 2 String arrays, to and cc , and 2 Strings, content and subject (obviously the api sends an email / ignore the attachment field for now) and I have no idea how I can set those parameters to my form-data in java.
