我想从我的 c 程序中启动一个进程，但我不想等待该程序完成.我可以使用 system() 启动该过程，但总是等待.有谁知道一旦进程开始就会返回的非阻塞"版本?
I want to launch a process from within my c program, but I don't want to wait for that program to finish. I can launch that process OK using system() but that always waits. Does anyone know of a 'non-blocking' version that will return as soon as the process has been started?
当原进程执行完毕后，子进程需要继续运行.
When the original process has finished executing, the child process needs to keep on running.

system("ls -l &");
&在命令行参数的末尾分叉你已经启动的任务.
