CMAP_...T_SET(3)

✨ CMAP_CONTEXT_SET — the CMAP_...T_SET(3) page, bestie edition ✨

okay so this is from the Corosync Cluster Engine Programmer's Manual, and it's literally just one tiny little function that holds onto a pointer for you. no cap, that's the whole vibe. let's get into it 💖

🌸 NAME 🌸

cmap_context_set — sets the context variable for a CMAP instance

like. it stores your lil context thing. that's it. that's the job. 💅

🎀 SYNOPSIS 🎀

#include <corosync/cmap.h>

cs_error_t cmap_context_set (cmap_handle_t handle, const void *context);

two args, one return, zero drama. slay.

🦋 DESCRIPTION 🦋

so the cmap_context_set function is used to store the context variable for a cmap instance. that's the whole thing bestie, that's the assignment 🫶

and here's the part that's lowkey iconic: it has no meaning inside libcmap itself and will not be touched by the library. like, libcmap is respectfully minding its own business. it's just holding your pointer for you, not looking at it, not judging it, not doing anything with it 🙈

so if you wanna get it back later? that's what cmap_context_get(3) is for. the retrieval arc. the reunion. periodt ✨

💖 RETURN VALUE 💖

this call returns the CS_OK value if successful. otherwise? an error is returned. that's it. that's the tea 😭
