Implement a program that prints a message “An instance is running” when executed more than once in the same session. For example, if we observe word application or Adobe reader in Windows, we can see only one instance in the task manager. How to implement it? Article compiled byVenki. ...
Each process provides the resources needed to execute a program.A process has a virtual虚拟 address space, executable code, open handles to system objects, a security context, a unique唯一的 process进程标识符,pid identifier, environment variables, a priority 优先级类class, minimum and maximum ...
But if you run a program directly as node app.js it will fail. Instead, run it like yarn node app.js this will initialize PnP.If you’re using zero-installs and accepting PRs from untrusted sources, it’s a good idea to add a cache check job somewhere in your CI pipeline. This ...
In the code below the order is always right and the program still prints the same result. This program has a race: the second call to Go races with Wait. Consider: the goroutine created by the first Go function could complete (along with println, Sleep, close) before the goroutine creat...
Thejesttesting framework is a great fit for writing tests against Node.js applications. Jest scans the files in the project for test files and executes them one a time. Install Jest with the--save-devoption, which tellsnpmthat the module is...
“b1” displays the line on the screen. The semaphore in this program guarantees that thread A has completed a1 before thread B begins b1. Here is how it works: if thread B gets to the wait statement first, it will find the initial value, zero, and it will block. Then when thread ...

The code in SEMAPHORE_STATE::Retire only sets TimePoint::completed for the larger value, not for earlier values. This is avoided only if the wait happens after the larger value is signaled, as there's a check against completed_.payload in SEMAPHORE_STATE::Wait. With the changes in this ...
