💖 REMCTL_NOOP(3) 💖

okay bestie, so this is a page from the remctl Library Reference, and it's literally all about one tiny little function called remctl_noop(). she's small but she's mighty, and she keeps ur connection alive. let's get into it 🫶

✨ NAME ✨

remctl_noop — send a NOOP message to a remctl server 💌

✨ SYNOPSIS ✨

#include <remctl.h>

int remctl_noop(struct remctl *r);

✨ DESCRIPTION ✨

okay so here's the tea 🍵: remctl_noop() sends a NOOP message to a remctl server, and then it reads back the NOOP response it's expecting. simple! iconic! she's basically a "hey bestie u still there??" text 💬

her main character use case? keeping a connection to a remctl server alive while u wait to issue further commands. think of it like a firewall with a session timeout that's about to ghost u — this is the function that keeps the vibe going 🔥

⚠️ but WAIT. the NOOP message needs protocol version 3 support on the server side. so the caller should be prepared for this function to just... fail 😭. and that failure means the connection could not be kept alive, and possibly that it got closed by the server. rude. in that case, the client will need to explicitly reopen the connection with remctl_open(). no shortcuts, bestie 💅

✨ RETURN VALUE ✨

remctl_noop() returns true on success and false on failure. periodt 💀

on failure, the caller should call remctl_error() to retrieve the error message. and ngl, besides plain network errors, this function may also fail if the server doesn't support protocol version 3. so it's giving "not all servers are ready for this energy" 🙈

✨ COMPATIBILITY ✨

this interface was added in version 3.0. she's a legacy icon at this point 👑
