CPG_C...XT_GET(3)

💖 CPG_CONTEXT_GET 💖

okay bestie, welcome to the cpg_context_get(3) page from the Corosync Cluster Engine Programmer's Manual ✨ no cap, this one's a shortie but she's important.

🌸 NAME 🌸

cpg_context_get — gets the context variable for a CPG instance 🎀

✨ SYNOPSIS ✨

#include <corosync/cpg.h>

int cpg_context_get(cpg_handle_t handle, void **context);

like. that's it. that's the whole vibe. 🦋

💅 DESCRIPTION 💅

so cpg_context_get does the thing where it retrieves the context variable that you previously stashed away using cpg_context_set(3). it's giving "hey remember that thing i gave you? give it back bestie" 💖

that's literally the whole function. she's simple, she's reliable, she's the friend who always remembers where you left your keys 🔥

👑 RETURN VALUE 👑

this call returns the CS_OK value if it worked, otherwise an error comes back at you 😭 like she tried her best but the universe said no.

💀 ERRORS 💀

ngl, the errors are undocumented. periodt. we don't know. nobody wrote them down. it's giving mystery ✨
