NAME

ATOMIC_XOR(3) - [ATOMIC:BIT MANIPULATION] Atomic bitwise OR operation

SYNOPSIS

call atomic_xor(atom, value [,stat] ) 

         subroutine atomic_xor(atom,value,stat)


          integer(atomic_int_kind)            :: atom[*]
          integer(atomic_int_kind),intent(in) :: value
          integer,intent(out),intent(out)     :: stat

CHARACTERISTICS

o ATOM is a scalar coarray or coindexed variable of integer type with atomic_int_kind kind.
o VALUE is a scalar of the same type as ATOM. If the kind is different, the value is converted to the kind of ATOM.
o STAT is a Scalar default-kind integer variable.

CHARACTERISTICS

DESCRIPTION

ATOMIC_XOR(3) atomically defines ATOM with the bitwise XOR between the values of ATOM and VALUE. When STAT is present and the invocation was successful, it is assigned the value 0. If it is present and the invocation 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.

OPTIONS

o ATOM : Scalar coarray or coindexed variable of integer type with atomic_int_kind kind.
o VALUE : Scalar of the same type as ATOM. If the kind is different, the value is converted to the kind of ATOM.
o STAT : (optional) Scalar default-kind integer variable.

EXAMPLES

Sample program: 

    program demo_atomic_xor
    use iso_fortran_env
    implicit none
    integer(atomic_int_kind) :: atom[*]
       call atomic_xor(atom[1], int(b’10100011101’))
    end program demo_atomic_xor
