The child process can then overlay itself with a different program (using exec) as required. [1] Each process may create many child processes but will have at most one parent process; if a process does not have a parent this usually indicates that it was created directly by the kernel.

var x1 = 0; // A global variable, because it is not in any function let x2 = 0; // Also global, this time because it is not in any block function f {var z = 'foxes', r = 'birds'; // 2 local variables m = 'fish'; // global, because it wasn't declared anywhere before function child {var r = 'monkeys'; // This variable is local and does not affect the "birds" r of the parent function. z ...
This special process detects when an orphan process terminates and then retrieves its exit status, allowing the system to deallocate the terminated child process. If a child process receives a signal, a waiting parent will then continue execution leaving an orphan process behind. [citation needed] Hence it is sometimes needed to check the ...
Describes the relationship between a child and its parent. The child is connected to its parent, but the parent is not connected to the child. Temporal coupling It is when two actions are bundled together into one module just because they happen to occur at the same time.

Parent is the process that receives the SIGCHLD signal on child's termination, whereas real parent is the thread that actually created this child process in a multithreaded environment. For a normal process, both these two values are same, but for a POSIX thread which acts as a process, these two values may be different. [2]
