多进程multiprocessing模块关于socket问题
本帖最后由 figofifa 于 2014-03-29 14:42 编辑sadfssssssssssssssssssssssssssssssssssss 一般会加那个括号吗。。recever = multiprocessing.Process(target = recv_proc)试试呢？ 回复 2# laike9m
还是不行。
回复 3# figofifa
现在只能执行一个进程，要不发进程，或者收进程，不能两个进程同时执行

把括号去掉能执行了，但提示两次socket.error: ，
代码如下：

global connection,sock1

activeTestSequence = activeTestSequence + 1

MessageHeader.append(activeTestCommandLength)
MessageHeader.append(activeTestCommand)
