🌸 SYNOPSIS 🌸

*result );

look at this signature, it's giving clean. three things go in, one int comes out. periodt. ✨

🎀 ARGUMENTS 🎀

• c — Controller instance. this is your controller, your main character, the one you're talking to. 🌈
• tas — Task field of the Command Dword 10 (cdw10). Indicates whether to perform a Registration, Deregistration, or Registration-update. so basically this lil field is the what are we doing here of the whole call, and it picks between the three tasks. lowkey important ngl. 👑
• result — The command-specific result returned by the DC upon command completion. the DC hands this back to you once the command is done, so it's the receipts. 🧾

🦋 DESCRIPTION 🦋

Perform registration task with a Discovery Controller (DC). that's the whole assignment, bestie. 🫧

Three tasks are supported, and they are, like, the entire menu:

• register
• deregister
• registration update

pick your fighter via tas and go. that's it. that's the function. 🔥

💜 RETURN 💜

• 0 on success. slay. 😌
• on failure -1 is returned and errno is set. so if it flops, check your errno, bestie, the info is right there. 😭

fr fr: 0 means we ate, -1 means read the errno. don't skip that step. 🙈
