ATOMIC_ADD
— Atomic ADD operationATOMIC_ADD(ATOM, VALUE)
atomically adds the value of VAR to the
variable ATOM. 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
ISO_FORTRAN_ENV
's STAT_STOPPED_IMAGE
and if the remote image has
failed, the value STAT_FAILED_IMAGE
.
CALL ATOMIC_ADD (ATOM, VALUE [, STAT])
ATOM | Scalar coarray or coindexed variable of integer
type with ATOMIC_INT_KIND kind.
|
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.
