debugfs_create_xul(9)

✨ debugfs_create_xul — bestie edition ✨

okay so this is from the Kernel API Manual (debugfs_create_xul(9)) and honestly? it's a little icon 💅

---

🌸 NAME 🌸

debugfs_create_xul — creates a debugfs file that reads and writes an unsigned long value, formatted in hexadecimal. that's it, that's the whole vibe. hex girl summer 🔥

---

🦋 SYNOPSIS 🦋

void debugfs_create_xul (const char *name , umode_t mode , struct dentry
*parent , unsigned long *value );

no cap, that's the whole signature. four args, zero drama 🫶

---

💖 ARGUMENTS 💖

• name — a pointer to a string holding the name of the file you want to create. name your baby, bestie 🎀
• mode — the permission that the file should have. yes, permissions. protect your peace 🔒
• parent — a pointer to the parent dentry for this file. this one should be a directory dentry if you set it. if this parameter is NULL, then the file gets created in the root of the debugfs filesystem — like, straight into the main character spot, no parent needed 👑
• value — a pointer to the variable that the file should read to and write from. so it's giving... two-way street. read and write. mutual. reciprocal. the file and the variable are literally in a relationship 😭

ngl, this whole thing is a void function — it returns nothing because it's too busy slaying. and remember: hex formatting is baked in, so don't come at it expecting decimal ✨
