gdb 調(diào)試一下造虎，是在后臺(tái)啟動(dòng)函數(shù)主進(jìn)程exit地方洒闸。

core位置

而且是兩個(gè)core的位置一樣，但是LWP不一樣可柿。

pthread_create是基于clone實(shí)現(xiàn)的, 創(chuàng)建出來的其實(shí)是進(jìn)程, 但這些進(jìn)程與父進(jìn)程共享很多東西,
共享的東西都不用復(fù)制給子進(jìn)程, 從而節(jié)省很多開銷, 因此,這些子進(jìn)程也叫輕量級進(jìn)程(light-weight process)簡稱LWP. 每個(gè)LWP都會(huì)與一個(gè)內(nèi)核線程綁定, 這樣它就可以作為獨(dú)立的調(diào)度實(shí)體參與cpu競爭.
LWP被pthread封裝后, 以線程面目示人, 它有自己的id, 這里要區(qū)分 phtread_create
給LWP分配的id, 和操作系統(tǒng)給LWP分配的進(jìn)程id. 這兩者是不同的, 前者用于標(biāo)志線程,可以暴露給
用戶, 后者其實(shí)就是進(jìn)程的id, 它沒有暴露出來, 必須通過系統(tǒng)調(diào)用來得到.

#include <stdio.h>
#include <unistd.h>
#include <sys/syscall.h>
#include <pthread.h>
 
//線程處理函數(shù)怯邪，輸出LWP號
void *func(void *argv)
{
    //獲取LWP的方法1
    int lwp;
    lwp = syscall(__NR_gettid);
    printf("lwp[%d]\n", lwp);
     
    //獲取LWP的方法2
    int lwp2;
    lwp2 = syscall(SYS_gettid);
    printf("lwp2[%d]\n", lwp2);
    sleep(50);
}
 
int main(void)
{
    pthread_t thd;
    pthread_create(&thd, NULL, func, NULL); //創(chuàng)建線程
    sleep(60);
    return 0;
}

<代碼和LWP說明抄網(wǎng)上的>
ps -eLF|grep pid命令可以查看進(jìn)程的線程ID（LWP號）
這個(gè)我們在程序中pthread_self()獲取的線程號并不是一樣的绊寻。
我通過gdb的命令確實(shí)看到core的位置是加解密函數(shù)里面的，但是沒有用啊。


加解密函數(shù)

兩個(gè)core的位置澄步，是因?yàn)槲覀兊暮笈_(tái)執(zhí)行函數(shù)冰蘑，如下：

void run_as_daemon(void) {
#ifndef _WIN32
    pid_t pid;
    signal(SIGHUP, SIG_IGN);
    signal(SIGTTOU, SIG_IGN);
    signal(SIGTTIN, SIG_IGN);
    signal(SIGTSTP, SIG_IGN);
    sleep(1);
    if ((pid = fork()) != 0) {
        if (pid < 0) {
            fprintf(stderr, "Fork error:%s", strerror(errno));
        }
        exit(0);
    }
    if (setsid() == -1) {
        fprintf(stderr, "setid error:%s", strerror(errno));
        exit(0);
    }
    signal(SIGHUP, SIG_IGN);
    if ((pid = fork()) != 0) {
        exit(0);
    }
    g_proc_run_status = PROC_RUNNING;
    int fd = open("/dev/null", O_RDWR);
    dup2(fd, STDOUT_FILENO);
    dup2(fd, STDERR_FILENO);
    close(fd);
#endif
}

除了改exit為_exit外，沒想到好辦法村缸，不過這樣就不清理資源了祠肥。
