context_lock_struct(9)

context_lock_struct(9) — declare or define a context lock struct 💅

✨ NAME ✨

okay so this page is from the Kernel API Manual, and the main character is context_lock_struct - declare or define a context lock struct. literally a helper to declare or define a struct type that is also a context lock. no cap, it's giving “struct but make it lock-aware.” 🎀

---

✨ SYNOPSIS ✨

context_lock_struct (name , ... );

---

✨ ARGUMENTS ✨

• name — struct name, bestie.
• ... — variable arguments, fr fr.

---

✨ DESCRIPTION ✨

helper to declare or define a struct type that is also a context lock. you can do it all cute and inline like this:

            context_lock_struct(my_handle) {
                    int foo;
                    long bar;
            };

            struct some_state {
                    ...
            };
            // ... declared elsewhere ...
            context_lock_struct(some_state);

so yeah, that's the whole vibe: either define the struct right there with context_lock_struct(my_handle), or use context_lock_struct(some_state) on a struct that was declared elsewhere. iconic. 🦋

---

✨ NOTE ✨

the implementation defines several helper functions that can acquire and release the context lock. that's the whole note, periodt. 💖
