[ CCode ( cname = "g_atomic_int_dec_and_test" ) ]
public bool dec_and_test (ref uint atomic)
Decrements the value of atomic by 1.
Think of this operation as an atomic version of `{ *atomic -= 1; return (*atomic == 0); }`.
This call acts as a full compiler and hardware memory barrier.
While atomic has a `volatile` qualifier, this is a historical artifact and the pointer passed to it should not be
`volatile`.
