Threads are a common building block for multitasking inside a single process. A thread is an independent stream of program execution that has access to the memory of other threads.
To start using threads, we will have to execute the following steps:
Write the command
import core.thread;.Write a function to perform your independent task.
If the thread needs to pause, use the static method
Thread.sleepfrom the thread to be paused.Create an additional thread with
auto thread = new Thread, passing it as a pointer to your function.Call
thread.startto begin execution.
Take a look at the following code:
import core.thread;
import core.atomic;
import std.stdio;
int count = 0;
shared(int) sharedCount = 0;
// this is the function that will run in our threads
void threadedFunction() {
foreach(i; 0 .. 5) {
writeln("thread running ", count++, " global: ", sharedCount);
Thread.sleep(1.seconds);
atomicOp!"+="(sharedCount, 1);
}
}
void main() {
auto thread ...
