以下代碼段有什麼問題？

Question

if (fork() == 0) { 
    printf("Here comes the directory listing\n"); 
    execlp("/bin/ls","ls",NULL); 
    printf("That is the end of the listing\n"); 
} else { 
    ... /*----Some legal stuff here */ 
} 

誰能告訴我這段代碼有什麼問題嗎？

Answer 1

一旦你調用execlp你的當前進程映像將被ls命令替換。你將不會得到Printf輸出。 execlp後無代碼運行

參考， - How do I printf() after a call to execlp() in a child process?
