===== 二、学习补充建议 ===== # 加深系统调用与库函数关系的理解 - 理解 printf()、fopen()、exit() 如何依赖内核资源和文件描述符,帮助在编程中更自然地使用重定向和进程控制。 # 多练习管道和信号交互场景 - 例如父子多进程通信、信号中断耗时计算、双向管道等,能加深对阻塞行为、EOF 信号、信号中断恢复等机制的理解。 # 关注边缘情况 - 如写端未关闭导致阻塞、僵尸进程积累、信号嵌套等,结合实验观察效果。 # 理解 <code>dup2()</code> 的优势 - 相比“关闭再打开”,dup2() 不会改变原文件描述符的打开状态,可以直接把已有文件描述符重定向到标准流,更安全高效。 总体来看,你对第十章核心概念掌握得不错,理解流程和逻辑清晰。补充实验和边缘场景理解会让你对 Unix/Linux 系统编程更加扎实。 哥们,如果你愿意,我可以帮你出几道实际小实验题,让你边写代码边验证这些概念,加深记忆。想做吗?
