CPG_I...ALIZE(3)

💖 CPG_ITERATION_FINALIZE 💖

okay bestie, so this is a page from the Corosync Cluster Engine Programmer's Manual — yes, the actual grown-up manual, and yes, we're doing this in the group chat voice. it's giving low-level C but make it cute. 🎀

✨ NAME ✨

cpg_iteration_finalize — the lil cleanup function that finalizes the iterator for members of CPG. it's the "we're done here, bye bye" of iterators. 🦋

🌸 SYNOPSIS 🌸

#include <corosync/cpg.h>

cs_error_t cpg_iteration_finalize (cpg_iteration_handle_t handle);

that's it. that's the whole vibe. one header, one function, one handle. iconic. 💅

🫶 DESCRIPTION 🫶

so cpg_iteration_finalize frees up the memory that's associated with an iteration — the one you got by calling cpg_iteration_initialize(3). like, that iterator was living in memory rent-free and this function is the eviction notice. 🧹✨

the handle argument is the iterator handle you got from cpg_iteration_initialize(3) in the first place. same handle, bestie. you hand it back, it cleans up.

no cap: if you don't finalize your iterators, that memory just sits there. so do it. be a responsible main character. 👑

⭐ RETURN VALUE ⭐

this call returns the CS_OK value if it's successful. slay.

and if your handle is invalid? you get CS_ERR_BAD_HANDLE back. 😭 that's the universe telling you the handle you passed is not it.
