CountdownLatch for C++ multi-threaded programming
CountdownLatch in C++
countdownlatch is a C++ library providing similar functionalities as availble with standard Java CountdownLatch class. It's main usage is: it allows one or more threads to wait until a set of operations being performed on other threads completes.
Below is an example regarding how to use the library
#include <unistd.h>
#include <thread>
#include <vector>
#include <iostream>
#include <countdownlatch.hpp>
void fun(clatch::countdownlatch *cl) {
cl->await();
std::cout << "Wait is over " << std::endl;
}
int main() {
auto cl = new clatch::countdownlatch(10);
int i = 0;
std::vector<std::thread*> ts;
while (i++ < 2) {
std::thread *t = new std::thread(fun, cl);
ts.push_back(t);
}
i = 0;
while (i++ < 10) {
sleep(1);
cl->count_down();
}
i = 0;
while (i < 2) {
ts[i++]->join();
}
i = 0;
while (i < 2) {
delete ts[i++];
}
delete cl;
return 0;
}
