A simple process of packet capture using libpcap:1. Obtain the device name: pcap_findalldevs. list all devices. Select the network devices to be listed and find them in the linked list. After obtaining the device name, release the linked list.Or

A few days ago, I saw this discussion on the csdn Forum: how to use variable parameters in macro definition? Http://expert.csdn.net/Expert/topic/2925/2925165.xml ). The owner hopes to define macro as follows: # Define fun1 (a, B,...) fun2 (_ file __,

In general, all program lines of the source program are compiled to generate the target code. However, in some special cases, you may only want to compile some program rows that meet the conditions. This is Conditional compilation.Programmers can

1# Ifdef _ debugVirtual void assertvalid () const; // assert (assert) valid (valid, correct)Virtual void dump (cdumpcontext & DC) const; // storage Context# EndifThese two functions are used for debugging. The first function checks availability,

During program debugging, we often need to output some debugging information. After the debugging is completed, we no longer need to use it. So how can I quickly switch between the debugging and publishing statuses? We usually use pre-compilation

In C ++, you can use predefined macros to implement Conditional compilation, so as to exclude some debugging code from the compilation scope during release. The elegant implementation of an encapsulation is as follows: 1 # define DEBUG 2 # if

Some settings for installing Elementary OS Freya When you buy a sofa, you should first consider the size (whether you can put it down or lie down), followed by the quality, brand, and perception ......, The function is the first priority, and the

C # pre-compiled commands with essential knowledge Author: Alen Source: IT expert network forum T|T--> Pre-compilation is generally used to prevent repeated inclusion and compilation of header files. The pre-compilation command indicates the

Reference: http://blog.csdn.net/alwaysrun/archive/2009/08/20/4467270.aspx Http://www.bianceng.cn/Programming/csharp/200910/11700.htm C and C ++ have a class of statements called Preprocessor commands. C # also has such a set of Preprocessor commands.

These macros are used for Conditional compilation. Generally, all the rows in the source program are compiled. However, sometimes you want to compile a part of the content only when certain conditions are met, that is, to specify the compilation

I. essential differences between debug and release compilation methods Debug is usually called a debug version. It contains debugging information without any optimization, so that programmers can debug programs easily. Release is called a release

C # pre-processor commands are called during compilation. Preprocessor directive tells C # Compiler which code to compile and how to handle specific errors and warnings. The C # pre-processor command also tells the C # editor about the code
