Function
GLibatomic_int_dec_and_test
since: 2.4
Declaration [src]
gboolean
g_atomic_int_dec_and_test (
volatile gint* atomic
)
Description [src]
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.
