上述过程,我们总结下就是:1、数据帧从外部网络到达网卡 2、网卡把帧DMA到内存Ring Buffer中 3、硬中断通知CPU 4、CPU响应硬中断,简单处理后发憷软中断 5、软中断进程处理软中断,调用网卡驱动注册的pool函数开始收包 6、帧被从Ring Buffer中摘下来,存储到skb中 7、协议层开始处理网络帧,并将处理完成后的数据放入...

首先,Winsock 异常 10035 WSAEWOULDBLOCK (WSAGetLastError) 的意识是 Output Buffer 已经满了,无法再写入数据。确切的说它其实不算是个错误,出现这种异常的绝大部分时候其实都不存在 Output Buffer 已满情况,而是处于一种“忙”的状态,而这种“忙”的状态还很大程度上是由于接收方造成的。意思就是你要发送的对象,对...
For TCP sockets, if the value you specify for thelenparameter is less than or equal to the send buffer size of the socket, the send process will be atomic; that is, either all of the data will be sent or none of it will be sent. If all of the data is sent, the return code is...

If OPTCD=NBUFFLST, CONTROL=DATA, and STYPE=REQ, AREA specifies the address of the data to be sent. If OPTCD=BUFFLST, CONTROL=DATA, and STYPE=REQ, AREA specifies the address of a buffer list which in turn specifies the data to be sent. This storage can be reused as soon as VTAM...
read(fd,(void *)buffer,sizeof(struct my_struct)); my_struct_server=(struct my_struct *)buffer; 在网络上传递数据时我们一般都是把数据转化为char类型的数据传递.接收的时候也是一样的注意的是我们没有必要在网络上传递指针(因为传递指针是没有任何意义的,我们必须传递指针所指向的内容) ...
If the application or another driver sent or requested data, the transfer buffer is passed to the driver by the framework. Alternatively, the client driver can allocate the transfer buffer and create the request object if the driver initiates the transfer on its own. ...
