因项目需要，实现一个nodejs模块** node-cppMsg**，用于与c/c++进行二进制数据通信：

1. 解析 C/C++传来的二进制数据为json对象；
2. 编码 json对象为c/c++能够解析二进制数据;

模块安装： npm install cppmsg 使用，参见 test.js

var cppMsg = require('cppmsg');
var msg_def = {
    msgHead:[
                ['mainType','int32'],
                ['subType', 'int32']
            ]
};
var msg = new cppMsg.msg(
    [
        ['reg','int32'],
        ['chkCode','int32'],
        ['iType','int32'],
        ['bMonitor', 'bool'],
        ['workPath','string',10],
        ['processID','uint32'],
        ['testObj','object', msg_def.msgHead],
        ['testint64','int64']
    ]
    );
var buff = msg.encodeMsg( {
        reg     : 2,
        chkCode : 0,
        iType   : 2,
        bMonitor : false,
        workPath : 'no 你 work',
        processID : 1234,
        
        testObj  :{
            mainType : 0x01020304,
            subType  : 0x0A0B0C0D
        },
        
        testint64 : 0xCDEF
    }  );
console.log( buff );
var data = msg.decodeMsg( buff );
console.log( data );
