我阅读了Google的本机客户端教程，了解如何多次构建我自己的基于C ++的PNaCl模块，不知怎的，我没有变得更聪明，我知道如果我想实现消息传递功能。我在.cc文件中有以下内容作为PNaCl代码的基础，所有这些都来自Googles的Hello World教程：
unsorted1据我所知，PNaCl模块不使用main（）函数，但是假设我有一个旧的C ++代码创建了2个数组unsorted2和#include <iostream>
#include <stdint.h>
#include <unistd.h>
#include <array>
// a function to create a random number between min and max
int32_t rangeRandomAlg (int32_t min, int32_t max) {
int32_t num = max - min + 1;
int32_t remainder = RAND_MAX % num;
int32_t x;
do {
x = rand();
} while (x >= RAND_MAX - remainder);
return min + x % num;
}
// a function to create arrays with random numbers
void unsortedArrays(int32_t unsorted1[], int32_t unsorted2[],int32_t arrayElements, int32_t minNum, int32_t maxNum){
for(int32_t i = 0; i <= arrayElements; i++) {
if (i < arrayElements/2) {
unsorted1[i] = rangeRandomAlg(minNum, maxNum);
} else {
unsorted2[i] = rangeRandomAlg(minNum, maxNum);
}
}
}
// the main function
int32_t main(int32_t argc, char *argv[]) {
// declare all the zises
int32_t minNum = 0;
int32_t maxNum = 100;
int32_t arrayElements = maxNum;
// the arrays
int32_t unsorted1[arrayElements/2];
int32_t unsorted2[arrayElements/2];
// fill the arrays with random numbers
unsortedArrays(unsorted1, unsorted2, arrayElements, minNum, maxNum);
return 0;
}
，其中包含我想要的随机数在我的PNaCl模块中使用：
HandleMessage()我的问题是我不太明白如何将此代码集成到PNaCl模块中并使用unsorted1函数将unsorted2和JavaScript数组发送回具有PostMesage()功能的HandleMessage()。我知道我必须使用数组而不是using System;
using System.Collections.Generic;
using System.Text;
using System.ComponentModel;
namespace FormsDataGridViewBinding
{
public class Person : INotifyPropertyChanged
{
public Person(string n, string name, string address)
{
_number = n;
_name = name;
_address = address;
}
public string Number
{
get { return _number; }
set
{
if (_number != value)
{
_number = value;
this.NotifyPropertyChanged("Number");
}
}
}
public string Name
{
get { return _name; }
set
{
if (_name != value)
{
_name = value;
this.NotifyPropertyChanged("Name");
}
}
}
public string Address
{
get { return _address; }
set
{
if (_address != value)
{
_address = value;
this.NotifyPropertyChanged("Address");
}
}
}
private string _number;
private string _name;
private string _address;
public event PropertyChangedEventHandler PropertyChanged;
private void NotifyPropertyChanged(string name)
{
if (PropertyChanged != null)
PropertyChanged(this, new PropertyChangedEventArgs(name));
}
}
}
函数中的字符串。
我希望能在这里得到一些帮助，因为我对这个完整的原生客户都很陌生。

变量= outRes1数组变量作为字符串发送到index.html中的JavaScript代码文件。您必须单独编写.nmf和index.html文件。如果有人想看到我的代码，那些具有此PNaCl模块的基本代码和工作代码的文件应该给我写评论，我会将这些代码发布到。
