💖 CMAP_...T_GET(3) 💖

okay bestie, so this one lives in the Corosync Cluster Engine Programmer's Manual and it's giving "tiny function, big main character energy". buckle up, it's short but it matters. 🎀

✨ NAME ✨

cmap_context_get — gets the context variable for a CMAP instance

like, it retrieves the lil' thing you stashed earlier. no cap. 🫶

🌸 SYNOPSIS 🌸

#include <corosync/cmap.h>

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

copy that exactly, bestie, don't freestyle the include. 💅

🦋 DESCRIPTION 🦋

so cmap_context_get is literally the function you call when you want to pull back the context variable you previously stored using cmap_context_set(3).

that's it. that's the whole job. it's the find-my-stash of CMAP. you put the vibe in, you get the vibe out. 🌈

💜 RETURN VALUE 💜

this call returns the CS_OK value if successful — slay — otherwise an error gets returned. 😭

⭐ SEE ALSO ⭐

and here's the ✨ error roster ✨, the whole squad, no one left out:

  • CS_ERR_TRY_AGAIN — resource temporarily unavailable (it's not ghosting you, it's just busy)
  • CS_ERR_INVALID_PARAM — invalid argument
  • CS_ERR_ACCESS — permission denied
  • CS_ERR_LIBRARY — the connection failed
  • CS_ERR_INTERRUPT — system call interrupted by a signal
  • CS_ERR_NOT_SUPPORTED — the requested protocol/functionality not supported
  • CS_ERR_MESSAGE_ERROR — incorrect auth message received
  • CS_ERR_NO_MEMORY — not enough memory to complete the requested task
lowkey if you see CS_ERR_NO_MEMORY it's giving "your machine needs a nap and a snack". not a vibe. 🙈

that's the whole page, bestie. this cutie is from the corosync Man Page, dated 23/01/2012 — yeah she's an elder but she still ate. 💖 periodt. 👑
