There're two things here; there's the C language, which it sounds like you've got some grasp on, but then there's the standard library and system calls. The system calls will be OS specific, so you probably want to look for a guide not just for C, but for operating systems. System calls are generally how the program interacts with anything outside itself (files, user input/output, timers, network, communication with other programs on the machine, etc).

Building a shell is a common assignment on many university level undergrad operating system courses. So my advice is: look for an article about building a shell from scratch for Linux OR look for an open operating systems course and check the syllabus to be sure it includes building a shell.

Wow, interesting. This must be a long term deal if GM is building the connector into their cars. I would worry about how long this partnership would last, like if I bought a GM car and a few years later lost Tesla supercharger access. But maybe both sides are happy and it'll continue for the long haul.

Thanks! Just to be clear, I didn't author the recipe. Just a happy user, so to speak

Would love this!
