debug_exception(9)

hey bestie, welcome to debug_exception(9) from the Kernel API Manual — the page for writing a binary debug entry and moving on to the next debug area. 💅

💖 NAME 💖

debug_exception — writes a binary debug entry to the active debug area (if level <= actual debug level) and switches to the next debug area.

Okay so it’s literally giving “log this binary debug entry into the active debug area when the level condition is true, then bounce to the next debug area.” ✨

✨ SYNOPSIS ✨

debug_entry_t * debug_exception (debug_info_t *id , int level , void
       *data , int length );

🎀 ARGUMENTS 🎀

• id — handle for debug log. 🫶
• level — debug level. 🌈
• data — pointer to data for debug entry. 🍓
• length — length of data in bytes. 📏

🌸 RETURN 🌸

• Address of written debug entry 👑
• NULL if error 💀
