This series alone is worth more than a bunch of paid Udemy courses. Thank you Nicholas for sharing your knowledge!

For anyone wondering, AF_INET is for IPv4 type addresses not TCP or UDP. AF_INET6 is used for IPv6 addresses. Only the _type_ parameter of the socket function is responsible for determining if it will be TCP or UDP.

Thank you for making this video. Is there any way you can link the project files in the description? I also have maybe a somewhat naive question, but since we are using windocks, I'm assuming it's meant for windows. Will this also be compatible with linux-based Operating systems? Have a great day!

@NicholasDayPhD 2 жыл бұрын

Hi there, yes, I have managed to code this on a Mac too (and confident it would be similar for Linux). The functions such as socket(), bind(), listen(), connect(), accept(), send(), recv() etc are the same for both Windows and Mac. Main differences are the low level Windows types (such as DWORD) are substituted for strings and integers with Mac. And rather than libraries winsock2.h and ws2tcpip.h, there are equivalent libraries such as arpa/inet.h, netdb.h, sys/socket.h, sys/types.h and unistd.h for Mac solutions.

@@NicholasDayPhD Hi Thank you very much for the detailed lectures. Would you please help me providing the info on how can we implement these in mac. Because we need two processes server and client, can we achieve this in mac terminal or do we need any IDE?

@NicholasDayPhD 2 жыл бұрын

@@raghuvaranpothuganti I've managed to run similar code via the IDE Visual Studio Code (to compile the source C++ code in to an executable application). You can also get Visual Studio for Mac, or you may even prefer the IDE CLion by JetBrains (same developers of IntelliJ). Basically, you just need an IDE to compile the source code! Once compiled, clicking on the application will launch a terminal window. For this basic example, I had two terminal windows on the the same Mac (one for server, one for client). However, you could configure the applications to talk to each other across a network. Hope that helps...

Putting "#define _WIN32_WINNT _WIN32_WINNT_VISTA" before "#include " and "#include " worked for me. This means Windows Vista is the oldest OS your code will work on though.

Why don't you just dive right in? Some of us hate "theory" just explain things while you code! Otherwise great video!

@kidkyle712 4 ай бұрын

Because that's stupid. "Diving right in" just encourages people to type over and barely learn anything. It's important to understand the concepts you're going to implement before actually implementing them.
