在程序开发时有时需要获取线程和进程ID以分析程序运行(1)windows下获取进程或线程ID通过调用系统提供的GetCurProcessId或GetNowThreadID来获取当前程序代码运行时的进程或线程ID示例代码：#include "windows.h"printf("now pid is %d", GetCurrentProcessId());printf("now tid is %d", GetCurrentThreadId());(2)linux下获取进程或线程ID通过getpid和gettid获取进程或线程ID示例代码：#include "unistd.h"printf("now pid is %d \n", getpid());printf("now tid is %d \n", gettid());(3)跨平台设计为了便于跨平台开发，可利用宏定义支持代码跨平台示例代码#ifndef __linux__#include "windows.h"#else#include "unistd.h"#endif#ifndef __linux__printf("now pid is %d \n", GetCurrentProcessId());printf("now tid is %d \n", GetCurrentThreadId());#elseprintf("now pid is %d \n", getpid());printf("now tid is %d \n", gettid());#endif————————————————版权声明：本文为CSDN博主「wily_1987」的原创文章，遵循 CC 4.0 BY-SA 版权协议，转载请附上原文出处链接及本声明。原文链接：https://blog.csdn.net/hanxv_1987/article/details/79509739
