ATOMIC_FETCH_AND
— Atomic bitwise AND operation with prior fetchATOMIC_AND(ATOM, VALUE)
atomically stores the value of ATOM in
OLD and defines ATOM with the bitwise AND 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
.

Atomic subroutine
CALL ATOMIC_FETCH_AND (ATOM, VALUE, OLD [, STAT])
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. |
