c++ - Making one of the threads to wait for least possible (almost zero) time -

-

A list is working on two types of threads (exclusive use of STL containers to be listed as threads after).

  • Adder thread: The item is being added to the list by several sources. / P>

  • Processor thread: A thread

< / P>

>

Problem: When the processor wants access to the thread list, it should be quick access (even if the other addendum thread is already waiting to reach the list , The processor thread should be given top priority). Ideally I'm not expecting almost any wait.

  1. Will thread priority be helped to solve it?
  2. Is there an algorithmic solution (alternative ways can be etc.)?

(The way the solution can be specific even for the Windows operating system, if this solves the problem)

I had not yet opened in the thread, but what about using two mutes for it? A adder_queue mutex and a mute x access .

In the Adder Code 

  std :: lock_guard & lt; Std :: mutex & gt; Queue_lock (adder_queue); Std :: lock_guard & lt; Std :: mutex & gt; Access_lock (access); // add operation

and the processor can display threads 

  std :: lock_guard & lt; Std :: mutex & gt; Access_lock (access); // Process Operation

Adder threads should now wait for adder_queue mutex before locking access and thus processor thread Always need to be present after the ongoing operation

java - Gradle dependencies: compile project by relative path -

Is it possible to specify a dependency on another gradeal project in the granular (in android studios) outside the current project limits? For example, with a relative path like this: dependence {collection project ('../../ stdlib / dagger'}} MyApp (path / user / foo / workspace / mypad) The app (Path / User / Foo / Workspace / MyPass / App) And I have an Android Library Project with 3 subdomules: stdlib (path is / user / foo / Utilities (Path / User / Foo / Workspace / Stadlib / Utilis) http (Path / User / Foo / Workspace / Stadlib / HT) / Li> What I have to do is compile the Dagger, Util, http module in the MyApp project. The Stidelib Library module under heavy development And MyApp will grow in the form of Growth, so I do not want to push them into a Mewen repository. I am a little change. is likely to add another Gredle projects in some way? I will push the study library into the Maven repository after the source is in search of a temp...
