node.js - (How) am I supposed to destroy a uv_async_t? -

after i'm done uv_async_t, i'm supposed destroy avoid leaks, right? glancing @ docs, appears i'm supposed use uv_close() this, takes uv_handle_t*, not uv_async_t*. furthermore, looks casting (as in uv_close((uv_handle_t *)async, null)) cause strict aliasing violation. i'm supposed anyway?

yes, have cast uv_async_t* uv_handle_t*. that's how libuv internally works.

all handles share base structure, iirc strict aliasing rules not broken because amounts casting first member of structure.

a note on example call uv_close: can free memory handle in close callback, not before, if pass null , handle allocated on heap won't know when can free memory.
