出现signal handler called的原因 signalhandlercalled是指在程序运行过程中,接收到一个信号后,系统会调用相应的信号处理函数,常见的原因包括程序错误、内存访问错误、系统调用错误等。此时,程序会跳转到信号处理函数中执行相应的操作,例如打印错误信息、关闭文件等。在处理完信号后,程序会继续执行原来的代码。需要注意的是...
>The mutex functions are not async-signal safe. What this means is that they should not be called from a signal handler. In particular, calling pthread_mutex_lock or pthread_mutex_unlock from a signal handler may deadlock the calling thread. 这里提到 async-signal-safe 的概念,一个函数是 asy...
