pub unsafe fn msgget(key: key_t, msgflg: i32) -> Result<i32, Errno>

Get a System V message queue identifier.

Example

let key = nc::IPC_PRIVATE;
let flags = nc::IPC_CREAT | nc::IPC_EXCL | (nc::S_IRUSR | nc::S_IWUSR) as i32;
let ret = unsafe { nc::msgget(key, flags) };
assert!(ret.is_ok());
let msq_id = ret.unwrap();
let mut buf = nc::msqid_ds_t::default();
let ret = unsafe { nc::msgctl(msq_id, nc::IPC_RMID, &mut buf) };
assert!(ret.is_ok());
