👑 Member Function Documentation 👑

💖 void wl_shm_pool_unref (struct wl_shm_pool * pool)

Unreference a shm_pool — literally what it says on the tin, bestie.

Parameters

• pool — the pool object 🫧

Drops a reference to a wl_shm_pool object. okay so listen, this is only necessary if the compositor has explicitly taken a reference with wl_shm_buffer_ref_pool(). if it hasn't? then don't worry about it, the pool gets automatically destroyed when appropriate. the universe handles it for you, it's very self-sufficient like that 🌈

See also

• wl_shm_buffer_ref_pool

fr fr, if you're out here calling wl_shm_pool_unref on a pool nobody ever ref'd, that's not the move. read the paragraph again. we love a careful queen 💅
