ATOMIC_ADD(3f)

DESCRIPTION
ATOMIC_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.

STANDARD
TS 18508 or later

CLASS
Atomic subroutine

SYNTAX
CALL ATOMIC_ADD (ATOM, VALUE [, STAT])

ARGUMENTS

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.

EXAMPLE
          program atomic
            use iso_fortran_env
            integer(atomic_int_kind) :: atom[*]
            call atomic_add (atom[1], this_image())
          end program atomic
