Hello

I'm doing test nacl sample.

basic sample is successed

Add a source to system() or popen() api.

The code is failed.

How can I use system() api?

my code is below.

#include "ppapi/cpp/instance.h"

#include "ppapi/cpp/module.h"

#include "ppapi/cpp/var.h"

#include <errno.h>

#include <cstdio>

#include <cstdlib>

#include <iostream>

class HelloTutorialInstance : public pp::Instance {

 public:

  explicit HelloTutorialInstance(PP_Instance instance) : pp::Instance(instance)

  {}

  virtual ~HelloTutorialInstance() {}

  const char* const kHelloString = "test_nacl";

  const char* const kReplyString = "hello 1111";

  virtual void HandleMessage(const pp::Var& var_message) {

    int s = system("ls");

    std::string bbb = strerror(errno);

    PostMessage(bbb.c_str());  

    PostMessage(errno);    

    PostMessage("----------");

  }

};

class HelloTutorialModule : public pp::Module {

 public:

  HelloTutorialModule() : pp::Module() {}

  virtual ~HelloTutorialModule() {}

  virtual pp::Instance* CreateInstance(PP_Instance instance) {

    return new HelloTutorialInstance(instance);

  }

};

namespace pp {

  Module* CreateModule() {

    return new HelloTutorialModule();

  }

}  // namespace pp

The short answer is no. Native Client programs do not have access to underlying system calls; they have essentially the same capabilities as JS code on the web. You'll need to use the PPAPI APIs in the browser.
