在Linux系统中,系统调用(system calls)是操作系统内核提供给用户程序使用操作系统服务的接口。系统调用允许用户程序与底层硬件进行交互,执行诸如文件操作、进程控制、网络通信等操作。其中,Linux系统调用system是一个非常重要且常用的系统调用,本文将重点介绍该系统调用的功能和使用方法。 system系统调用主要用于在用户程序中...
In this article, we discussed the interrupted system calls in Linux. First, we saw that interrupted system calls are system calls that may be blocked forever. The reception of a signal by a process interrupts the execution of interrupted system calls. We also learned that the OS may either ...
