coding point of view is as follows: TCP communication requires server-side listening Listen, receiving client connection request accept, waiting for client connect to establish a connection before sending and receiving packets (recv/send). However, the concept of UDP server and client is not obvious, the server side is the receiving end need to bind the port, waiting for the arrival of the client's data. Subsequent data can be sent and received (RECVFROM/SENDTO) work. Reference: http://blog.

Function call relationships in the tcp protocol stack during tcp three-way handshake in the Linux kernel-Linux general technology-Linux programming and kernel information. For more information, see the following. Recently, I need to modify a set of tcp protocol stacks. I simply looked at the function calling process of the kernel tcp protocol stack. It is just a rough process and I did not make a detailed investigation, take a closer look at the chang

white hairSummarize the treatment of SHUT_WR or shut_rdwr:1) Stop transmitting the data (no more calls to the write operation), Discard unsent data in the buffer (write is called but the underlying TCP stack is not yet sent)2) Stop waiting for a confirmation message for the sent data, sent unconfirmed data no longer re-sent"Disconnection Process Summary"1) Close only reduces the reference count of the socket file, and when the count is reduced to 0, the operating system runs a TCP disconnection

/3915Source: mu Net, Dependency simple understanding, dependency is a class A used to another class B, and the use of the relationship is contingency, temporary, very weak, but the change of Class B will affect the Class A. For example, if someone wants to cross the river, they need to borrow a boat, and the relationship between the man and the ship is dependent. At the code level, for Class B as a parameter, Class A is used in a method. In UML class diagram design, a dependency relationship is

1. When the exception is referred to the user for processing, the exception handling method Veh-〉seh-〉vch is called in the following order.2. When veh indicates that an exception was handled, it is not passed to SEH, but the exception is passed to VCH.3. When the veh is not processed, it is passed to Seh.4. When all the exception handlers for SEH are not able to handle the exception, the default Seh (that is, Ueh, only the SEH) handler function is invoked.5. When SEH handles an exception and sta

Source: Liu XuefengThe inheritance relationship is:object -> Animal -> Dog -> HuskyThen, isinstance() you can tell us whether an object is of a certain type. Create 3 types of objects First:>>> a = Animal()>>> d = Dog()>>> h = Husky()Then, Judge:>>> isinstance(h, Husky)True>>> isinstance(h, Dog)True>>> isinstance(d, Husky)False子类可以看做父类对象，但反过来不可以。"Python" Inheritance relationships and Isinstance

coding specification, write native code that interacts with Java, generally is the conversion of data type, the data class of C + + is converted into Java can recognize, or vice versa. Also because of this, I think JNI is actually adapter, as the data transfer layer exists, the specific JNI general operation, I then share;D/C + + development, coding to implement business logic, or to invoke the NDK to provide local APIs or libraries to complete the development of specific features on the Androi

software does not have a higher demand for the processing power of the chip, the chip makers will not invest money to develop new chips. For example, in a small embedded device (such as a rice cooker), the software may only need to complete the countdown function, in order to develop a 24-core 48-thread Xeon processor, and then use the 2560-stream processor GTX1080 to control the time display "rendering", it is obviously ridiculous.In general, the development of software and chips complements e
