STRUCT ITERATE_MODULE_CTX(9)

💖 NAME 💖

okay so bestie, welcome to the <struct iterate_module_ctx(9)> page from the Kernel API Manual ✨ — and the name tea is literally: struct iterate_module_ctx — HW module iterator. periodt 💅

✨ SYNOPSIS ✨

here's the struct in all its main-character glory, formatting preserved fr fr:

struct iterate_module_ctx {
    void (*fn)(struct hl_device *hdev, int block, int inst, u32 offset,
struct iterate_module_ctx *ctx);
    void *data;
    int rc;
 };

Don't come for the spacing, bestie — that's literally how it's listed 😭💅

🎀 Members 🎀

• fn — the function to apply to each HW module instance. like, every single one gets the callback treatment ✨
• data — optional internal data to the function iterator. think lil' extra payload for the callback vibe 🎀
• rc — return code for optional use of iterator/iterator-caller. it's there if they wanna use it, iykyk 💫

🌈 SEE ALSO 🌈

the extended universe is huge, bestie — here's every single reference, exactly as listed:
