strcpy and memcpy are standard C library functions that have the following characteristics. strcpy provides a copy of the string. That is, strcpy is used only for string copying, and it also copies the end character of the string, not just the string content. MEMCPY provides a common memory copy. That is, memcpy has no limitations on what needs to be replicated, so it is more versatile. MEM Series functions are often in the interview when the knowledge points, we need to master the principles

MEM Series functions are often in the interview when the knowledge points, we need to master the principles of these three functions and code implementation, to be able to accurately write the code. memcpy, Memset, and memset three functions need to be included with the bottom file during use: In C#include In C + +#include memcpy The memcpy function is the memory copy function in C/s + +, which starts at the beginning of the memory address indicated by source SRC, and copies n bytes to the st

interface to be filtered. if a router has at least two network interfaces, you can use this option to filter only the data passed through the specified interface. For example: Tcpdump-I eth0 only displays all headers on the eth0 interface. The options src, dst, port, host, net, ether, and gateway include additional options such as src, dst, port, host, net, and ehost. They are used to identify the source a

. If no type is specified, the default type is host. The second is a keyword that determines the direction of transmission, mainly including src,dst,dst or SRC,DST and SRC, which indicate the direction of the transmission. For example, SRC 210.27.48.2, which indicates that the source address in the IP packet is 210.27.48.2, D
