ENUM CPPI5_TR_TRIGGER(9)

💅 enum cppi5_tr_trigger(9) 💅

okay so bestie, you're reading the Kernel API Manual and we're about to talk about enum cppi5_tr_trigger — the TR Flags TRIGGERx field. That field literally specifies the type of trigger used to enable the TR to transfer data as specified by the TRIGGERx_TYPE field. like, that's the whole job. it's giving "small enum, big responsibility" ✨

🌸 NAME 🌸

enum cppi5_tr_trigger — the TR Flags TRIGGERx field that specifies the type of trigger used to enable the TR to transfer data as specified by the TRIGGERx_TYPE field 🫶

---

✨ SYNOPSIS ✨

enum cppi5_tr_trigger {
    CPPI5_TR_TRIGGER_NONE ,
    CPPI5_TR_TRIGGER_GLOBAL0 ,
    CPPI5_TR_TRIGGER_GLOBAL1 ,
    CPPI5_TR_TRIGGER_LOCAL_EVENT

};

---

🎀 Constants 🎀

okay so there are exactly four of them and honestly? each one is iconic in its own way 💅

• CPPI5_TR_TRIGGER_NONE — no trigger. that's it. nothing. the void. she's not getting triggered today 💀
• CPPI5_TR_TRIGGER_GLOBAL0 — Global trigger 0 🌍✨
• CPPI5_TR_TRIGGER_GLOBAL1 — Global trigger 1 🌍⭐ (yes, the sequel)
• CPPI5_TR_TRIGGER_LOCAL_EVENT — Local Event 🎀 keeping it close to home, we love a lowkey queen

ngl bestie, that's the whole enum. four constants, zero drama, and yet somehow the TR can't do anything without picking one. main character energy fr fr 👑
