ATOMIC_DEFINE(3f)

DESCRIPTION
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 ISO_FORTRAN_ENV's STAT_STOPPED_IMAGE and if the remote image has failed, the value STAT_FAILED_IMAGE.

STANDARD
Fortran 2008 and later; with STAT, TS 18508 or later

CLASS
Atomic subroutine

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

ARGUMENTS

ATOM Scalar coarray or coindexed variable of either integer type with ATOMIC_INT_KIND kind or logical type with ATOMIC_LOGICAL_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_define (atom[1], this_image())
          end program atomic
