ATOMIC_FETCH_XOR(3f)

DESCRIPTION
ATOMIC_XOR(ATOM, VALUE) atomically stores the value of ATOM in OLD and defines ATOM with the bitwise XOR between the values of ATOM and VALUE. 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_FETCH_XOR (ATOM, VALUE, OLD [, 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. OLD Scalar of the same type and kind as ATOM. STAT (optional) Scalar default-kind integer variable.

EXAMPLE
          program atomic
            use iso_fortran_env
            integer(atomic_int_kind) :: atom[*], old
            call atomic_fetch_xor (atom[1], int(b'10100011101'), old)
          end program atomic
