ATOMIC_DEFINE
— Setting a variable atomicallyATOMIC_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
. CALL ATOMIC_DEFINE (ATOM, VALUE [, STAT])
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. |
program atomic use iso_fortran_env integer(atomic_int_kind) :: atom[*] call atomic_define (atom[1], this_image()) end program atomic
