seq_mangle_path(9)

💅 seq_mangle_path(9) — like, the Kernel API Manual, but make it make sense 🎀

okay so bestie, welcome to seq_mangle_path(9), straight out of the Kernel API Manual ✨ this one's a lil utility icon and honestly it's giving "small but mighty" energy, so let's get into it 🫶

---

✨ NAME ✨

seq_mangle_path — mangle and copy path to buffer beginning 💫 (yes that's the whole vibe: mangle it, copy it, put it at the start of the buffer, slay)

---

🌸 SYNOPSIS 🌸

char * seq_mangle_path (char *s , const char *p , const char *esc );

that's the whole signature, no cap 🔥 copy it exactly, don't @ me

---

🦋 ARGUMENTS 🦋

• s — buffer start 💖 this is where the magic lands, the destination, the main character of the buffer world
• p — beginning of path in above buffer 🌈 yes, "above buffer" = inside s, so p points at where the path starts living
• esc — set of characters that need escaping 😭 these are the lil troublemakers that get the octal treatment

---

🧚 DESCRIPTION 🧚

okay so here's the tea ☕: it copies the path from p to s, and every single occurrence of a character from esc gets replaced with the usual octal escape 💅 that's it, that's the function, and it ate fr fr.

when it's done it returns a pointer past the last written character in s 👑 and if things go sideways? it returns NULL in case of failure 💀 so like, always vibe check your return value, iykyk.
