A lightweight & stable cross-platform support library with a focus on asynchronous socket I/O, support win32 & linux & apple & android & wp8 & wp8.1-universal & win10-universal
The core design is reference from https://github.com/chriskohlhoff/asio but very small.
This lib is used by project http://hongjing.qq.com/ and run at thousands of devices.
support IPv6-only network.
support multi-connections at one thread.
support deadline timer.
processing tcp sticky internal, user do not need to care it.

#Simiple usage:

1. Only compile src\xxsocket.cpp with your project; For gcc, you must add --std=c++11 compile flag
   
2. demo code:

#include "xxsocket.h"
using namespace purelib::inet;
void test_connect() 
{
   xxsocket clientsock;
   // The interface xpconnect_n will detect whether localhost is IPV6 only network automatically
   // and connect the ipv4 server by V4MAPPED address.
   if(0 == clientsock.xpconnect_n("www.baidu.com", 443, std::chrono::seconds(5)/* connect timeout 5 seconds */))
   {
       printf("connect succeed\n");
   }
}

#Asio usage:
cpp intergation: Compile src\xxsocket.cpp src\masio.cpp with your project
cpptest: https://github.com/halx99/mini-asio/blob/master/test/test/cpptest.cpp

lua intergation:

1. Compile src\xxsocket.cpp src\masio.cpp src\ibinarystream.cpp src\obinarystream.cpp [src\lmasio.cpp(for c++17) or src\lmasio11.cpp(for c++11)] with your project
2. call luaopen_masio after LUA VM initialized.

#Quick test at linux platform with gcc compiler:
g++ src/xxsocket.cpp src/masio.cpp test/test/cpptest.cpp --std=c++11 -lpthread -I./src -o cpptest && ./cpptest

#pitfall: For Microsoft Visual Studio, if your project has specific precompiled header, you should include it at head of xxsocket.cpp or specific the compile option: C/C++ --> Advance -->'Forced Include File' to it(such as pch.h).
