seq_escape_mem(9)

✨ seq_escape_mem(9) ✨

okay so this is a page straight out of the Kernel API Manual bestie, and it's all about seq_escape_mem — the little function that prints your data into a buffer while escaping the sketchy characters 💅

---

🎀 NAME 🎀

seq_escape_mem — print data into buffer, escaping some characters 🦋

---

🌸 SYNOPSIS 🌸

void seq_escape_mem (struct seq_file *m , const char *src , size_t len ,
unsigned int flags , const char *esc );

---

💖 ARGUMENTS 💖

• m — the target buffer, aka where the good stuff goes 🎯
• src — the source buffer, aka where the good stuff comes from 📥
• len — size of source buffer, gotta know how much we're working with 📏
• flags — flags to pass to string_escape_mem, yes they get forwarded, no we don't touch them 🚩
• esc — set of characters that need escaping, the ones that would otherwise cause chaos 😱

---

👑 DESCRIPTION 👑

Puts data into buffer, replacing each occurrence of character from given class (defined by flags and esc) with printable escaped sequence. literally every single one, no cap 🔥

Use seq_has_overflowed to check for errors. like please actually check it, don't just vibe and hope 🙈

ngl if you skip the overflow check that's on you bestie 💀
