# 或者: from multiprocessing.util import _afterfork_registry [as 别名]
def child(cls, n, conn):
if n > 1:
p = multiprocessing.Process(target=cls.child, args=(n-1, conn))
p.start()
p.join()
else:
conn.send(len(util._afterfork_registry))
conn.close() 示例2: test_lock
# 需要导入模块: from multiprocessing import util [as 别名]
# 或者: from multiprocessing.util import _afterfork_registry [as 别名]
def test_lock(self):
r, w = multiprocessing.Pipe(False)
