ATOMIC_OR
Atomic Intrinsic Subroutine (Generic): Performs atomic bitwise OR.
CALL ATOMIC_OR (atom, value [, stat])
atom |
(Input; output) Must be a scalar coarray or coindexed object and of type integer with kind ATOMIC_INT_KIND. It becomes defined with the value of ior (atom, int (value, ATOMIC_INT_KIND)) if no error occurs. Otherwise, it becomes undefined. ATOMIC_INT_KIND is a named constant in the intrinsic module ISO_FORTRAN_ENV. |
value |
(Input) Must be a scalar integer. The value of value must be representable as an integer with kind ATOMIC_INT_KIND. |
stat |
(Output; optional) Must be a non-coindexed integer scalar with a decimal exponent range of at least four (KIND=2 or greater). The value assigned to stat is specified in Overview of Atomic Subroutines. If stat is not present and an error condition occurs, error termination is initiated. |
Example
Consider the following:
CALL ATOMIC_OR (N[4], 10)
If the value of N on image 4 is 9 when the atomic operation is initiated, the value of N on image 4 is 11 when the operation completes and no error condition occurs during the subroutine reference.
