pthread_create函数：/*创建一个线程*/
原型：int pthread_create（（pthread_t *thread, pthread_attr_t *attr, void *（*start_routine）（void *）, void *arg）
用法：#include <pthread.h>
功能：创建线程（实际上就是确定调用该线程函数的入口点），在线程创建以后，就开始运行相关的线程函数。
说明：thread：线程标识符；
attr：线程属性设置，可以用NULL，表示使用默认的属性；
start_routine：线程运行函数的起始地址；
arg：传递给start_routine的参数，NULL表示无参数；
返回值：成功，返回0；出错，返回-1。
pthread_join函数：/*等待子线程执行完毕,函数的调用者在等待子线程退出后才继续执行！ */
pthread_exit函数：
线程通过调用pthread_exit函数终止执行，就如同进程在结束时调用exit函数一样。这个函数的作用是，终止调用它的线程并返回一个指向某个对象的指针。
pthread_exit ("thread all done"); // 重点看 pthread_exit() 的参数，是一个字串，这个参数的指针可以通过
xxxx
在高通原始代码中,打开 dump 后，预览会很卡顿,这使得不方便重现问题，利用多线程优化 dump 数据:
