Examples

Build

  • On Linux

Execute command:

mkdir build
cd build
cmake ../examples -DCMAKE_BUILD_TYPE=Release
cmake --build . -DCMAKE_BUILD_TYPE=Release
  • On Windows

Ensure cmake.exe is in your PATH, then execute

mkdir build
cd build
cmake.exe ../examples
cmake.exe --build . --config Release

Note for Windows

We use linux as an example to show how to run the examples. If you are using Windows, you may need WSL to use linux utility like nc to test your executable (Windows program). So you need to install WSL. And if you want your linux utility to communicate with your Windows program, you should use ip directly instead of localhost. For example, you have a server running on Windows using port 8899, you want to connect it via nc, you should execute following command in WSL:

> cat /etc/resolv.conf
> nc <ip_from_above> <port>

bench_task

Task<> benchmark.

> ./bench_task/bench_task
task: 2.582392 ns/iteration
iter: 1.696028 ns/iteration
naive: 0.242517 ns/iteration
  • task: Use Task<> to simulate generator
  • iter: tranditional iterator, but inline not allowed for operator++ .
  • naive: raw loop (or inlined tranditional iterator).

The performance of iter should be the up bound for the Task<>. See source for more details.

chatroom_server

In the first terminal

> ./chatroom_server/chatroom_server

In the second terminal

> nc localhost 8899       #1 <- time order
**** server received **** #1
<1>: second               #4

In the third terminal

> nc localhost 8899       #2
**** server received **** #2
second                    #3
**** server received **** #3

You can open more terminals.

echo_server

In the first terminal

> ./echo_server/echo_server
echo server listening localhost:8899

In the second terminal

> nc localhost 8899
I love you,
I love you,

You can open more terminals.

http_helloworld_server

In the first terminal

> ./http_helloworld_server/http_helloworld_server

In the second terminal

> curl localhost:8899
<html>
<head><title>Hello, World</title></head>
<body>Hello, World</body>
</html>

You open browser to open 127.0.0.1:8899 .

> ./pingpong/pingpong_server

In the second terminal

> ./pingpong/pingpong_client
