🌸 NAME 🌸

rpma_peer_cfg_set_direct_write_to_pmem — declare direct write to PMEM support ✨

like. that's literally the whole job. it declares a thing. it doesn't do the thing. it just ~declares~ the thing 💅

---

🦋 SYNOPSIS 🦋

#include <librpma.h>

struct rpma_peer_cfg;
int rpma_peer_cfg_set_direct_write_to_pmem(struct rpma_peer_cfg *pcfg, bool supported);

ok so first you gotta #include <librpma.h> — no include, no vibes, that's the rule 🔥 and yes there's an opaque struct rpma_peer_cfg; hanging out up there because that's just how this library rolls, you don't get to peek inside her 👑

---

🎀 DESCRIPTION 🎀

rpma_peer_cfg_set_direct_write_to_pmem() declares the support of the direct write to PMEM.

that's it. that's the sentence. she's a one-line queen and honestly? iconic. you pass in your pcfg and you tell her whether direct write to PMEM is supported or not, and she goes and records that fact. no drama, no side quests 🌈

---

💜 RETURN VALUE 💜

• returns 0 when everything's good — slay, we love a success ✨
• returns a negative error code when it's not — so like, check that return value bestie, fr fr 😭

💀 ERRORS 💀

rpma_peer_cfg_set_direct_write_to_pmem() can fail with this one single error, and she's very specific about it:

• RPMA_E_INVAL — pcfg is NULL 🙈 like girl you handed her nothing, what did you expect

no cap: if you pass NULL, that's the error you're getting. don't be shocked. be prepared 💅
