C手写一个多线程，供java调用

package com.tigger;

public class MyThread {
    static {
　　　　　　//装载库，保证jvm在启动的时候就会装载
        System.loadLibrary("TiggerThreadNative");
    }

    public static void main(String[] args) {
        MyThread myThread=new MyThread();
        myThread.start0();
    }

    private native void start0();
}

#include <pthread.h>
#include <stdio.h>
#include "com_tigger_MyThread.h" //需导入刚刚编译的.h文件
pthread_t pid;
void* thread_entity(void* arg)
{
    while(1){
        usleep(100);
        printf("I am new Thread\n");
    }
}
//此方法名需要从刚刚编译的.h头文件里复制方法名，这里参数写死
JNIEXPORT void JNICALL Java_com_tigger_MyThread_start0 (JNIEnv * evn, jobject c1)
 {
    pthread_create(&pid,NULL,thread_entity,NULL);
    while(1){
        usleep(100);
        printf("I am main\n");
    }
 }
 int main(){
    return 0;
 }
