How can a C/C++ program put itself into background?

Question

What\'s the best way for a running C or C++ program that\'s been launched from the command line to put itself into the background, equivalent to if the user had launched fro

Answer 1

The way it's typically done on Unix-like OSes is to fork() at the beginning and exit from the parent. This won't work on Windows, but is much more elegant than launching another process where forking exists.

Answer 2

/**Deamonize*/

pid_t pid;
pid = fork(); /**father makes a little deamon(son)*/
if(pid>0)
exit(0); /**father dies*/
while(1){
printf("Hello I'm your little deamon %d\n",pid); /**The child deamon goes on*/
sleep(1)
}

/** try 'nohup' in linux(usage: nohup <command> &) */
