Lcomm command declares an uninitialized data-local common memory region that does not allow access from outside the local assembler code. It is used in the following format:. comm Symbol, lengthSymbol is the sign assigned to the memory area, and length is the number of bytes contained in the memory area. one benefit of declaring data in a BSS segment is that the data is not included in the executable program, and the data

The most important application of Node.js is the server order. One of the main objectives of the design node.js is to provide a highly scalable server environment. This is the difference between the node and the V8 engine that we introduced at the beginning of this chapter. In addition to using the V8 engine to parse JavaScript, Node provides a highly optimized application library to improve server efficiency. For example, HTTP modules are rewritten for fast non-blocking HTTP servers with C. Le

There is a kind of moving, called Nei surface, there is a mechanism called module mechanism. Obviously, this kind of modular mechanism brings convenience to those Linux enthusiasts, because the modular mechanism means that people can divide the huge Linux kernel into many small modules. For developers writing device drivers, since then they can write device drivers do not need to compile her into the kernel, not reboot machine, she is just a module, when you need her, you can carry her into the

C # aims to combine the high productivity of Visual Basic with the capability of C ++ itself. With the "using" command, you can use various types of members in the namespace without any difficulty.That is, if there is no using system, it is also possible to complete system in front of the statement. The following code is equivalent:Using system;Class hello{Static void main (){Console. writeline ("Hello,
