运行在后台的linuxÇ一个新的子进程 [英] Running a new child process in background C linux

问题描述

我想在后台运行一个新的进程，因此将有可能继续与父进程的工作。

I am trying to run a new process in background so it will be possible to continue working with parent process.

我用叉子然后EXECL。我试图添加到execl的命令的参数及放大器;但它不工作：

I used fork then execl. I tried to add to the execl command the argument & but it doesn't work:

execl("newproc","newproc","arg1","&",NULL);

请问有什么解决办法吗？

Is there any solution?

推荐答案

的问题是，＆安培; 不是一个命令行选项来计划。相反，它是在后台将一个命令仅仅是特殊的shell语法。的后台程序的显着特点是，它们不连接到一个终端，并且终端没有等待的过程来完成。正确功能是守护进程（）。做一个男人守护对如何使用它念起来。

The problem is that & is not a command line option to programs. Instead, it is merely special shell syntax which puts a command in the background. The distinguishing feature of background programs is that they are not connected to a terminal, and the terminal is not waiting for the process to complete. The proper function is daemon(). Do a man daemon to read up on how it is used.
