pvalloc(3)

✨ pvalloc ✨

okay bestie, so we're talking about pvalloc — the function that hands you page-sized, page-aligned memory. it's giving very specific, very picky, and honestly? iconic for it. 💅

💖 LIBRARY 💖

Standard C library (libc, -lc) 🫶

🌸 SYNOPSIS 🌸

#include <malloc.h>

[[deprecated]] void *pvalloc(size_t size);

ngl, see that [[deprecated]] right there? yeah. the compiler is side-eyeing this function and so should you. ⚠️

🦋 DESCRIPTION 🦋

so like, pvalloc() is basically valloc()'s slightly extra sibling. it does the same page-aligned thing, BUT it also rounds size up to the next multiple of the system page size. no half-pages, no crumbs, no "close enough" — it's all the way rounded up, periodt. ✨

🎀 ATTRIBUTES 🎀

for the whole explanation of what these terms even mean, go peek at attributes(7). it's the lore, iykyk 📖

• Interface: pvalloc()
• Attribute: Thread safety
• Value: MT-Unsafe init 💀

so yeah, the thread safety vibe check says MT-Unsafe init — don't be out here calling it all willy-nilly from threads during init, bestie. 😭

👑 STANDARDS 👑

GNU. that's it, that's the standard. slay, GNU. 🌈

⭐ HISTORY ⭐

glibc 2.0. an elder. a legend. a true original 🫡✨
