最近刚开始玩C++,遇到一些基础问题,下面就是其中之一,将源代码公布一下方便大家查找。
linux C++ 类成员函数中创建线程,且能访问类中其他成员变量.
重点:将线程执行函数声明为非类成员函数,通过参数*arg 将this指针传入线程函数体中。
test.h
#ifndef TEST_H
#define TEST_H
class test
{
public:
test();
~test();
public:
int p;
void sayHello(int r);
void createThread();
private:
int q;
};
#endif
#define TEST_H
class test
{
public:
test();
~test();
public:
int p;
void sayHello(int r);
void createThread();
private:
int q;
};
#endif
test.cpp
#include "test.h"
#include <string>
#include<pthread.h>
test::test()
{}
test::~test()
{}
void *threadFunction(void *arg)
{
test *obj = (test *)arg;
printf("get p:%d",obj->p);
obj->sayHello(12);
for(;;);
}
void test::sayHello(int r)
{
printf("Hello world %d!/n", r);
}
void test::createThread()
{
p = 1;
q = 2;
pthread_t threadID;
pthread_create(&threadID, NULL, threadFunction, this);
getchar();
}
