ATOMIC_OR(3) - [ATOMIC:BIT MANIPULATION] Atomic bitwise OR operation
SYNOPSIS
call atomic_or(atom, value [,stat] )
subroutine atomic_or(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.
DESCRIPTION
ATOMIC_OR(3) atomically defines ATOM with the bitwise OR 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_or use iso_fortran_env implicit none integer(atomic_int_kind) :: atom[*] call atomic_or(atom[1], int(b’10100011101’)) end program demo_atomic_or
