💖 rpma_mr_dereg(3) — RPMA Programmer's Manual 💖

okay bestie, sit down, hydrate, and let me tell you about rpma_mr_dereg — it lives in the RPMA Programmer's Manual and it's literally the little cleanup icon you need in your life. ✨

🌸 NAME 🌸

rpma_mr_dereg — delete a local memory registration object

no cap, that's the whole job. it deletes. it deregisters. it says bye. 👑

🎀 SYNOPSIS 🎀

#include <librpma.h>

struct rpma_mr_local;
int rpma_mr_dereg(struct rpma_mr_local **mr_ptr);

look at that signature. gorgeous. flawless. a little pointer-to-a-pointer moment, because we're changing the thing it points at. iykyk. 💅

🦋 DESCRIPTION 🦋

rpma_mr_dereg() deregisters a memory region and deletes a local memory registration object. that's it, that's the vibe. it's the closing credits of your memory registration's main character arc. 🎬

⭐ RETURN VALUE ⭐

rpma_mr_dereg() returns 0 on success, or a negative error code on failure. slay when it's zero, sad girl hours when it's negative. 😭

heads up: rpma_mr_dereg() does not set the *mr_ptr value to NULL on failure. so do not — i repeat, do NOT — assume your pointer got tidied up for you. she stays exactly where she was. 🫶

💀 ERRORS 💀

rpma_mr_dereg() can fail with the following errors:

  • RPMA_E_INVAL — mr_ptr is NULL. bestie. you gave it nothing. it cannot work with nothing. 🙈
  • RPMA_E_PROVIDER — memory deregistration failed. the provider said no and honestly we have to respect it. 💔
