linux - DIFFERENT TASKS ASSIGNED TO DIFFERENT INSTANCES OF FORK() OF A PROCESS IN C

Can I assign different task to different instances of fork() of a process in C ? like for example:

program.c has been forked 3 times

int main()
{
    pid_t pid;
    pid = fork();
    pid = fork();
    pid = fork();
}

now to every instance of fork() I want to do different thing, Can I do this? with forks ? or any other method if favorable? :)

PS: I am testing Real Time Linux and want to check the performance of the Context Switching through forks through Time Constraint.

You can use posix process..

posix_spawn( &Pid,ProgramPath.c_str(), & FileActions,& SpawnAttr,argv,envp);

Check its documentation here.
