一、什么是观察点？观察点是一个特殊的断点，当表达式的值发生变化时，它将中断下来。表达式可以是一个变量的值，也可以包含由运算符组合的一个或多个变量的值，例如'a+b'。有时被称为数据断点(VC里面就称之为数据断点)。二、观察点常用命令watch：写观察点rwatch：读观察点awtach：读写断

测试代码#include<cstdint>#include<thread>intg_v=0;voidthread_func1(){for(inti=1;i<100;++i){if(i%4==0)++g_v;}}voidthread_func2(){for(inti=1;i<100;++i){if(i%2==0)g_v++;}}

设置读观察点1.例子#include<stdio.h>#include<pthread.h>#include<unistd.h>inta=0;void*thread1_func(void*p_arg){while(1){a++;sleep(10);}}void*thread2_func(void*p_arg){while(1){a++;sleep(10

设置读写观察点1.例子：#include<stdio.h>#include<pthread.h>#include<unistd.h>inta=0;void*thread1_func(void*p_arg){while(1){a++;sleep(10);}}void*thread2_func(void*p_arg){while(1){a++;sleep(1

设置观察点1.例子#include<stdio.h>#include<pthread.h>#include<unistd.h>inta=0;void*thread1_func(void*p_arg){ while(1) { a++; sleep(10); }}intmain(intargc,char*argv[]){ pthread_tt1; pthread_create(&t1,NUL

设置观察点1.例子：#include<stdio.h>#include<pthread.h>typedefstruct{inta;intb;intc;intd;pthread_mutex_tmutex;}ex_st;intmain(void){ex_stst={1,2,3,4,PTHREAD_MUTEX_INITIALIZER};printf("%d,%d,%d,%d\n&
