PMEMBLK_NBLOCK(3)

✨ pmemblk_bsize(3) ✨

okay bestie, welcome to the PMDK Programmer's Manual 💖 this one's about pmemblk_bsize() and pmemblk_nblock() — both DEPRECATED btw, so like, noted, but we're still gonna learn it fr fr

---

🌸 NAME 🌸

pmemblk_bsize()(DEPRECATED), pmemblk_nblock()(DEPRECATED) — check number of available blocks or usable space in block memory pool

like... it's literally giving "how much room do we have in here" energy 🎀

---

💅 SYNOPSIS 💅

#include <libpmemblk.h>

size_t pmemblk_bsize(PMEMblkpool *pbp);
size_t pmemblk_nblock(PMEMblkpool *pbp);

---

🦋 DESCRIPTION 🦋

so the pmemblk_bsize() function returns the block size of the specified block memory pool, that is, the value which was passed as bsize to pmemblk_create(). and pbp must be a block memory pool handle as returned by pmemblk_open(3) or pmemblk_create(3). no substitutes, bestie, it's not gonna vibe check a random pointer for you 🙈

the pmemblk_nblock() function returns the usable space in the block memory pool. same deal — pbp must be a block memory pool handle as returned by pmemblk_open(3) or pmemblk_create(3). 👑

---

⭐ RETURN VALUE ⭐

• the pmemblk_bsize() function returns the block size of the specified block memory pool. simple, iconic, no notes 💖
• the pmemblk_nblock() function returns the usable space in the block memory pool, expressed as the number of blocks available. so like, not bytes — blocks, okay? don't come for me 🔥

and that's the whole page, bestie 🫶 remember these two are DEPRECATED, so if you're out here writing fresh code, maybe check what the cool kids are using instead. still, knowledge is knowledge, and you ate 💅

mwah 💋 this was PMDK, dated 2023-05-31 — that's the version and the date, no cap. bye bestie, go read some more manpages 🌸✨
