This is the html code:

I want to create a CGDisplayStream with the CGDisplayStreamCreateWithDispatchQueue c function, which expects an CGDisplayStreamFrameAvailableHandler as parameter. CGDisplayStreamFrameAvailableHandler is an objective-c block. I tried to use a c++ lambda but this doesnt work:

No viable conversion from '(lambda at ###RECTRACTED###)' to 'CGDisplayStreamFrameAvailableHandler' (aka 'void (^)(CGDisplayStreamFrameStatus, uint64_t, IOSurfaceRef _Nullable, CGDisplayStreamUpdateRef _Nullable)')

I found: Objective-C Blocks in C but this doesnt really help, since they didnt explain what is needed to create an objective-c block in plain c or c++.

How can i create a valid object which i can pass to CGDisplayStreamCreateWithDispatchQueue?

I feel like what I want to accomplish is simple: create a custom WordPress Gutenberg Block that auto-populates with the author name and image and is not editable. Then render this block on the frontend post.

I've gone at this from a lot of different angles, and I think what I need is a Dynamic Block

First issue is the wp.data.select("core/editor").getCurrentPostId() doesn't load the post ID. But then I'll be honest, I don't know if the return would even have the author info I want anyway. Any guidance is most appreciated.

I am using a bunch of synchron functions from my own "old" libary. These are used to backup files, compress them and upload them per example. For further use i would like to change these to async functions. Please forgive me my following long intro, but the problem needs a bit background..

i have found several information on how to convert this:

A great book : Concurrency in C# Cookbook from Stephen Cleary.

Here is example Pattern i am tryping to adept:

• https://docs.microsoft.com/en-us/dotnet/standard/asynchronous-programming-patterns/interop-with-other-asynchronous-patterns-and-types#EAP

Also some posts here:

• C#: HttpClient, File upload progress when uploading multiple file as MultipartFormDataContent

• System.Net.Http.HttpClient.PostAsync blocks and never returns

• Library Design Guide

Main Points:

• Use Async /Await all the way done
• Don't wrap synchron Methods in asychron pattern with result or wait. Use await everywhere possible
• Wrap EAP Pattern Methods to Tasks
• Avoid Using Task.Run in Libaries
• Use ConfigureAwait(False) in Libaries
• Use Task.Run instead in your UI
• Use IProgress to post progress

My basic class looks like this:

I am studying Java 11 concurrency model and I see that a true singleton can be obtained via LazyHolder pattern. In particular, that page says that:

Since the class initialization phase is guaranteed by the JLS to be sequential, i.e., non-concurrent, no further synchronization is required...

Ok so I understand that the static fields are initializated only once in sequence (so

Based on the dynamic block example for retrieving a recent posts block, I'm trying to create a block that retrieves pages.

In the php server component I changed:

I'm creating some custom dynamic blocks for WordPress Gutenberg editor (following this link ).

I use the PHP render for these blocks, meaning I have this code on save:

Asume the following code:

I updated to Android Studio 3. I can build the "debug" apk but now I cannot build the "release" apk. I get this error:
