util: use shm_open for in-memory files shm_open is a POSIX function creating an in-memory file. Using it simplifies the code and removes the dependency on XDG_RUNTIME_DIR. The only downside is that we need to generate a random name for the shm file. 2018-10-26 18:38:23 +02:00			`#ifndef UTIL_SHM_H`

util/shm: add allocate_shm_file_pair This function behaves like allocate_shm_file, except it also returns a read-only FD. This is useful to share the same segment of memory with many Wayland clients. 2021-08-07 13:46:38 +02:00			`#include <stdbool.h>`
