cppi5_tr_init(9)

okay bestie, welcome to the cppi5_tr_init(9) page from the Kernel API Manual. this is the init-TR-record function, and we're about to give it a full vibe check. no cap, every detail is staying. 💖✨

🌸 NAME 🌸

cppi5_tr_init — Init TR record. that's the name, and honestly it ate. 💅

✨ SYNOPSIS ✨

void cppi5_tr_init (cppi5_tr_flags_t *flags , enum cppi5_tr_types type ,
       bool static_tr , bool wait , enum cppi5_tr_event_size event_size , u32
       cmd_id );

🎀 ARGUMENTS 🎀

okay so here's the whole argument lineup, and yes, every single one matters:

• flags — pointer to the TR's flags. it's giving "hold my flags." 🎀
• type — the TR type. lowkey important. ✨
• static_tr — says whether the TR is static. periodt.
• wait — wait for the TR to complete before allowing the next TR to start. yes, it's the "wait your turn" energy. 💅
• event_size — output event generation cfg. that's it, that's the cfg. 🦋
• cmd_id — TR identifier (application specifics). keep it cute and app-specific. 🙈

💖 DESCRIPTION 💖

Init TR record.

that's the entire description, bestie. no side quests, no bonus lore — it inits the TR record and that's iconic. 👑
