mmap_unmap(3)

✨ mmap_unmap ✨

okay so this is the manual page for mmap_unmap, from the Library Functions Manual bestie 💖 like it lives in section 3 of the man pages, the library functions girlies 🎀

💅 NAME 💅

mmap_unmap — unmap an existing memory mapping

yep that's the whole job. it unmaps. it's giving cleanup era 🧹✨

---

🦋 SYNTAX 🦋

ok so first you gotta pull in the header, like:

#include <libowfat/mmap.h>

and then the actual function, she's short and sweet:

int mmap_unmap(char* mapped,size_t maplen);

no cap, that's it. mapped is your pointer, maplen is your size, and she returns an int 💜

---

🌸 DESCRIPTION 🌸

okay so listen 🫶 mmap_unmap removes a memory mapping. like, it takes that mapping you made and it's like "ok bye bestie" 👋

but here's the tea — it only handles mappings that were established by one of these three:

• mmap_read
• mmap_private
• mmap_shared

so if you made your mapping with one of those, mmap_unmap is your girl 💖 if you didn't... that's a different conversation, and this page is not having it 🙈
