UNIX for Dummies Questions & Answers

I know that the fork() can use for create a child process as following

pid_t child_pid;
int child_status;

child_pid = fork();

switch (child_pid)
{
case -1:
perror("fork");
exit(1);
case 0:
printf("hello world\n");
exit(0);
default:
wait(&child_status);
}

but this code can only create only one child process but I want to create more than one child process,but I don't know how to do.

Anyone who good at "process in Unix" or who know how to do this,
Help me please. Thank you very much.

You need not to be "process in Unix" 's guru for what you are asking for ...
Maybe u need a basic sense of ... coding
Don't get me wrong but, u just have to loop to create more than 1 process with fork, something like

Code:

for (i=0; i<some_number; i++) do_something();

Ever considered using threads as an alternative, instead of spawning so many new process ?

Look at this post and our tutorial section.
