我们会借助一些崩溃日志收集库来定位和排查线上的崩溃信息，但是有些崩溃堆栈所提供的信息有限又不是必现...
线程0崩溃:线程0是指主线程,当主线程出现错误或异常导致崩溃时,就会出现线程0崩溃的情况。主线程通常负责程序的初始化和管理,如果主线程崩溃,整个程序可能会终止运行。 SIGABRT异常: SIGABRT是一种信号,表示程序异常终止。当程序发生严重错误或违反了某些条件时,会发送SIGABRT信号来终止程序的执行。SIGABRT通常由程序自身...
OK,如果int sig是0呢,这是一个保留信号,一个作用是用来判断线程是不是还活着。 我们来看一下pthread_kill的返回值: 成功:0 线程不存在:ESRCH 信号不合法:EINVAL 所以,pthread_kill(threadid,0)就很有用啦。 int kill_rc = pthread_kill(thread_id,0); if(kill_rc == ESRCH) printf("the specified th...
4. 可以使用pthread_kill对指定的线程发送信号 APUE的说法:每个线程都有自己的信号屏蔽字,但是信号的处理是进程中所有的线程共享的,这意味着尽管单个线程可以阻止某些信号,但当线程修改了与某个信号相关的处理行为后,所 有的线程都共享这个处理行为的改变。这样如果一个线程选择忽略某个信号，而其他线程可...
