Wireshark is a network protocol detection tool that supports windows and UNIX platforms. I generally only use Wireshark on Windows platforms. If it is Linux, I directly use tcpdump, in my work environment, Linux generally only has a character interface. Generally, Linux uses tcpdump, or uses tcpdump to capture p

If you have read the touch code in the sample, you will find a CC in the sample. node_touch_capture_event event, and CC. node_touch_event is an engine-level event like a touch event. Let's take a look at its differences with a touch event.
A touch capture event has a higher priority than a touch event. In other words, a touch capture event responds first than a touch event and has the right to send a touch

Abstract:Many video software (such as video conferencing and videophone) development is applied to video capture technology. Microsoft provides software developers with a vfw sdk dedicated for video capture, which provides a standard interface for video capture in windows and greatly reduces the difficulty of program development. Because the vfw sdk only has VC a

Every time you use string mode matching, you always have to go through the instructions on the Lua official website. There is no detailed description on the Internet, and many friends have asked me about the content, in fact, there are three difficulties:
I am not familiar with the regular expression of Lua;
The other is unfamiliar with the usage of several functions provided by the string library in Lua;
Another point is that the string library of Lua puts forward a new concept called
