topa_insert_table(9)

✨ NAME ✨

okay so bestie, this is topa_insert_table(9) from the Kernel API Manual, and it's literally the function that inserts a ToPA table into a buffer. no cap, that's the whole vibe. 👑💅

🌸 SYNOPSIS 🌸

void topa_insert_table (struct pt_buffer *buf , struct topa *topa );

🎀 ARGUMENTS 🎀

• buf — PT buffer that's being extended. of course. 🫶
• topa — New topa table to be inserted. slay. ✨

🦋 DESCRIPTION 🦋

okay so here's the tea: if it's the first table in this buffer, then it sets up the buffer's pointers accordingly. main character setup moment ✨

otherwise — and yes, there's an otherwise, bestie — it adds a END=1 link entry to topa to the current "last" table and adjusts the last table pointer to topa. periodt. 💅🔥
