if create_dummy_fds:
for i in range(0, 256):
if not cls._is_fd_assigned(i):

fd = reduction.recv_handle(conn)
if msvcrt:
fd = msvcrt.open_osfhandle(fd, os.O_WRONLY)
os.write(fd, data)
os.close(fd) 示例2: test_missing_fd_transfer
# 需要导入模块: from multiprocessing import reduction [as 别名]
# 或者: from multiprocessing.reduction import recv_handle [as 别名]
def test_missing_fd_transfer(self):
# Check that exception is raised when received data is not
# accompanied by a file descriptor in ancillary data.
