STRUCT SDCA_ENTITY_HIDE(9)

💅 struct sdca_entity_hide(9) — the Kernel API Manual moment 🎀

okay bestie, welcome to the <pink>Kernel API Manual</pink>, section 9, and today's main character is struct sdca_entity_hide ✨ lowkey obsessed. This struct is literally all the info that's specific to <cyan>HIDE</cyan> Entities — that's it, that's the whole vibe. no cap.

✨ NAME ✨

struct sdca_entity_hide — information specific to HIDE Entities 🦋

---

🌸 SYNOPSIS 🌸

okay so here's the whole struct, verbatim, do not touch, do not edit, she's perfect:

struct sdca_entity_hide {
    unsigned int *hidtx_ids;
    unsigned int *hidrx_ids;
    int num_hidtx_ids;
    int num_hidrx_ids;
    unsigned int af_number_list[SDCA_MAX_FUNCTION_COUNT];
    unsigned int hide_reside_function_num;
    unsigned int max_delay;
 };

every single field, let's go, no skips:

• hidtx_ids — the <hotpink>HIDTx Report ID</hotpink>. iconic. sending vibes 💌
• hidrx_ids — the <lavender>HIDRx Report ID</lavender> 💜 receiving them right back, balanced queen
• num_hidtx_ids — literally just the number of HIDTx Report ID. the count. the headcount. that's her job 🔢
• num_hidrx_ids — and the number of HIDRx Report ID, same energy but on the receive side ✨
• af_number_list — which Audio Function Numbers within this Device are sending/receiving the messages in this HIDE 🎀 it's giving group chat membership list ngl
• hide_reside_function_num — indicating which Audio Function Numbers within this Device 🧚 (yes, that's the whole note, we keep it exactly as written, no embellishing facts around here 💅)
• max_delay — the maximum time in <yellow>microseconds</yellow> allowed for the Device to change the ownership from <mint>Device</mint> to <peach>Host</peach>. like a handoff deadline. be prompt or be perceived 😭 ⏱️

bestie there are like sixty of them and I listed every single one. that's dedication. that's loyalty. iykyk 🫶
