vs2019 c语言配置pthreads多线程

1.下载pthreads-w32-2-9-1-release.zip文件，解压

2. 项目属性=》=》vc++目录=》包含目录=》添加 xxx\pthreads-w32-2-9-1-release\Pre-built.2\include

3.项目属性=》=》vc++目录=》库目录=》添加xxx\pthreads-w32-2-9-1-release\Pre-built.2\lib\x64

4.项目属性=》=》链接器=》输入=》附加依赖项=》添加pthreadVC2.lib

5.测试代码：

#include <stdio.h>

#include <stdlib.h>

#include <pthread.h>

#include <string.h>

void* print_message_function(void* ptr);

struct node_ {

int index;

int name;

}node;

int main()

{

int tmp1, tmp2;

void* retval;

pthread_t thread1, thread2;

char* message1 = "thread1";

char* message2 = "thread2";

node_ param;

param.index = 5;

param.name = 8888;

int ret_thrd1, ret_thrd2;

ret_thrd1 = pthread_create(&thread1, NULL, print_message_function, &param);

ret_thrd2 = pthread_create(&thread2, NULL, print_message_function, &param);

// 线程创建成功，返回0,失败返回失败号

if (ret_thrd1 != 0) {

printf("线程1创建失败\n");

}

else {

printf("线程1创建成功\n");

}

if (ret_thrd2 != 0) {

printf("线程2创建失败\n");

}

else {

printf("线程2创建成功\n");

}

//同样，pthread_join的返回值成功为0

tmp1 = pthread_join(thread1, &retval);

printf("thread1 return value(retval) is %d\n", (int)retval);

printf("thread1 return value(tmp) is %d\n", tmp1);

if (tmp1 != 0) {

printf("cannot join with thread1\n");

}

printf("thread1 end\n");

tmp2 = pthread_join(thread1, &retval);

printf("thread2 return value(retval) is %d\n", (int)retval);

printf("thread2 return value(tmp) is %d\n", tmp1);

if (tmp2 != 0) {

printf("cannot join with thread2\n");

}

printf("thread2 end\n");

}

void* print_message_function(void* ptr) {

node_* pc = (node_*)ptr;

int i = 0;

for (i; i < 5; i++) {

printf("%d:%d\n", pc->name, i);

}

return NULL;

}

6.如果代码运行报错：找不到pthreadVC2.dll。解决方法：将pthreadVC2.dll拷贝到项目的Debug目录下

7.如果代码运行报错：“timespec”;”struct”类型重定义。解决方法：在pthread.h在第35行加入如下代码：#define HAVE_STRUCT_TIMESPEC
