about pthread's question, help me please!

hello everyone,

I want to use pthread to new a new thread, but at build my project that have a problem.

The log said, can not open file “pthread.h”: No such file or directory.

how I to do.

my code:

#ifndef SENDDATA_H
#define SENDDATA_H

#include <pthread.h>
#include “cocos2d.h”

class SendData
{
public:

SendData(void);
virtual ~SendData(void);

SendData GetSelf();

protected:
private:
SendData* m_pSendData;
pthread_t tid;

int UpDate();
};

#endif

BTW

if I write it like this:

<cocos2dx/platform/third_party/win32/pthread/pthread.h>

The log said that “sched.h”: No such file or directory

i want to use it on my android project. Can I use it?
