How to name a process

In the previous example, we identified the processes and how to pass a variable to the target function. However, it is very useful to associate a name to the processes as debugging an application requires the processes to be well marked and identifiable.

How to do it...

The procedure to name a process is similar to that described for the threading library (see the recipe How to determine the current thread in Chapter 2, Thread-based Parallelism, of the present book.)

In the main program, we create a process with a name and a process without a name. Here, the common target is the foo()function:
