✨ rpma_peer_cfg_get_direct_write_to_pmem — check direct write to PMEM support ✨

okay bestie, sit down, hydrate, and let's talk about the RPMA Programmer's Manual 💖 this one lives in section 3, and it's genuinely so cute and simple you're gonna scream.

🌸 NAME 🌸

rpma_peer_cfg_get_direct_write_to_pmem — check direct write to PMEM support

like. that's it. that's the whole job. she checks, she reports, she slays 💅

---

🦋 SYNOPSIS 🦋

#include <librpma.h>

struct rpma_peer_cfg;
int rpma_peer_cfg_get_direct_write_to_pmem(
                const struct rpma_peer_cfg *pcfg, bool *supported);

so you've got your opaque lil struct rpma_peer_cfg (mysterious, main character energy, we don't see her internals 👑) and then the function itself takes a const struct rpma_peer_cfg *pcfg and a bool *supported and hands you back an int. periodt.

---

🎀 DESCRIPTION 🎀

rpma_peer_cfg_get_direct_write_to_pmem() checks the support of the direct write to PMEM.

that's the vibe check fr fr — you give her a peer config, she tells you whether direct write to PMEM is a thing that's supported. no drama, no side quests, just the answer ✨

---

💜 RETURN VALUE 💜

• 0 on success — ate, no notes 🫶
• a negative error code on failure — not the moment, but we move 😭

so basically: 0 means we're so back, negative means we are unwell.

---

🌈 ERRORS 🌈

rpma_peer_cfg_get_direct_write_to_pmem() can fail with the following error:

• RPMA_E_INVAL — pcfg or supported are NULL

lowkey if you passed a NULL in there, that's on you bestie 💀 she's not gonna guess what you meant. pcfg and supported both gotta be real, actual, existing pointers. no cap.
