ATOMIC_DEFINE— Setting a variable atomically
ATOMIC_DEFINE(ATOM, VALUE)defines the variable ATOM with the value VALUE atomically. 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_DEFINE (ATOM, VALUE [, STAT])
|ATOM||Scalar coarray or coindexed variable of either 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.
|STAT||(optional) Scalar default-kind integer variable.
