ATOMIC_REF— Obtaining the value of a variable atomically
ATOMIC_DEFINE(ATOM, VALUE)atomically assigns the value of the variable ATOM to VALUE. When STAT is present and the invocation was successful, it is assigned the value 0. If it is present and the invocation 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_REF(VALUE, ATOM [, STAT])
|VALUE||Scalar of the same type as ATOM. If the kind
is different, the value is converted to the kind of ATOM.
|ATOM||Scalar coarray or coindexed variable of either integer
type with |
|STAT||(optional) Scalar default-kind integer variable.
