exchange

Description:

[ Version ( since = "2.74" ) ]
[ CCode ( cname = "g_atomic_int_exchange" ) ]
public uint exchange (ref uint atomic, uint newval)

Sets the atomic to newval and returns the old value from atomic.

This exchange is done atomically.

Think of this operation as an atomic version of `{ tmp = *atomic; *atomic = val; return tmp; }`.

This call acts as a full compiler and hardware memory barrier.

atomic	a pointer to a int or uint
newval	the value to replace with

the value of atomic before the exchange, signed
