ATOMIC_FETCH_AND— Atomic bitwise AND operation with prior fetch
ATOMIC_AND(ATOM, VALUE)atomically stores the value of ATOM in OLD and defines ATOM with the bitwise AND between the values of ATOM and VALUE. When STAT is present and the invokation was successful, it is assigned the value 0. If it is present and the invokation has failed, it is assigned a positive value; in particular, for a coindexed ATOM, if the remote image has stopped, it is assigned the value of
STAT_STOPPED_IMAGEand if the remote image has failed, the value
CALL ATOMIC_FETCH_AND (ATOM, VALUE, OLD [, STAT])
|ATOM||Scalar coarray or coindexed variable of integer
type with |
|VALUE||Scalar of the same type as ATOM. If the kind
is different, the value is converted to the kind of ATOM.
|OLD||Scalar of the same type and kind as ATOM.
|STAT||(optional) Scalar default-kind integer variable.
