# Socket++
[](https://www.travis-ci.org/shuai132/SocketPP)
a lightweight C++ TCP socket library, powered by epoll on Linux platform and kqueue on macOS/Unix.
## Features:
* High performance and high concurrenc benefit from epoll/kqueue
* Support send queue with thread safe
* Automatic memory management and ensure performance by c++ move semantics
* Multi-instance support
* Multiplatform support, Linux/macOS and most Unix-like OS.
## Requirements:
* C++11
## Build:
```bash
mkdir build && cd build && cmake .. && make
```
## Usage:
* simple echo server
```cpp
#include "SocketPP.h"
using namespace SocketPP;
int main() {
const int port = 6000;
TCPServer server(port);
server.setRecvHandle([&] (const Message& message) {
server.send(message);
});
return server.loop();
}
```
and then use nc tools, or run client example:
```bash
nc localhost 6000
```
or
```cpp
#include "SocketPP.h"
using namespace SocketPP;
int main() {
const int port = 6000;
TCPClient client("127.0.0.1", port);
client.setConnHandle([&] (const TCPStream& stream) {
client.send("hello");
});
client.setRecvHandle([&] (const Message& message) {
printf("on receive: msg:%s", message.rawMsg.toString().c_str());
});
return client.loop();
}
```
