原子API范例（多线程多进程混合）:¶

使用本模块需如下步骤:

创建子进程所需要的函数, UIntAPIs, IntAPIs, BytearrayAPIs, StringAPIs, SetAPIs, ListAPIs子进程当中可以创建多线程def process_run(a):

     def subthread_run(a):

         a.array_sub_and_fetch(b'\x0F')

     threadlist = []

     for t in range(5000):

         threadlist.append(Thread(target=subthread_run, args=(a,)))

     for t in range(5000):

         threadlist[t].start()

     for t in range(5000):

         threadlist[t].join()
create the shared bytearray

a = atomic_bytearray(b'ab', length=7, paddingdirection='r', paddingbytes=b'012', mode='m')
start processes/threads to utilize the shared bytearray

    processlist = []

    for p in range(2):

        processlist.append(Process(target=process_run, args=(a,)))

    for p in range(2):

        processlist[p].start()

    for p in range(2):

        processlist[p].join()

    assert a.value == int.to_bytes(27411031864108609,length=8,byteorder='big')
