It is just a small header file and does most of the simple stuff you need without using a big template-based approach like boost(no offence, I like boost!). This tutorial explains how to get the MAC address on Linux using C++. Defined in 2 files as a function: include/linux/ofnet.h, line 27 (as a function) net/core/ofnet.c, line 125 (as a function). You can use cmd+a to select all, cmd+c to copy. Defined in 1 files as a prototype: include/linux/ofnet.h, line 16 (as a prototype). There is an excellent answer from Shreevardhan below with this source code (This code may throw): #include įor (const auto & entry : fs::directory_iterator(path)) Getting MAC addresses in Java Baeldung Web23 juin 2015 Get the local MAC address in C/C++. the file /sys/class/net/eth0/address carries your mac adress as simple string you can read with fopen() / fscanf() / fclose(). Type /sbin/ifconfig this will list your IP address as well your MAC address. All you have to do is check out bytes 2 through 8 and you are done. Apparently Microsoft uses your MAC address to help it create a universally unique identifier. In C++17 there is now an official way to list files of your file system: std::filesystem. One quick way to find out your MAC address, which is very hacky and I wouldn’t recommend would be to create a sequential Uuid.
