python multiprocessing - access the process name inside the function called with Process.start(target=func)

You can use the current_process function:

from multiprocessing import Process, current_process

def somefunc():
    print current_process().name

if __name__ == '__main__':
    p = Process(target=somefunc)
    p.start()
    print p.name

Instead of passing target argument, override the run method. From there, you can invoke someFunc and pass the process object to it.

The name is not an OS level concept. It is Python level and it is not automatic that the process you execute in even has a Process object anywhere.
