interop

Additional information

When the destroy clause appears on the depobj construct, the destroy-var argument may be omitted. This syntax has been deprecated.

Semantics

If the destroy clause appears on a depobj construct and destroy-var is not speciﬁed, the eﬀect is as if destroy-var refers to the same OpenMP depend object as the depobj argument of the construct. The syntax of the destroy clause on the depobj construct that does not specify destroy-var has been deprecated. When the destroy clause appears on a depobj construct, the state of destroy-var is set to uninitialized.

When the destroy clause appears on an interop construct, the interop-type is inferred based on the interop-type used to initialize destroy-var, and destroy-var is set to the value of omp_interop_none after resources associated with destroy-var are released. The object referred to by destroy-var is unusable after destruction and the eﬀect of using values associated with it is unspeciﬁed until it is initialized again by another interop construct.

Restrictions

destroy-var must be non-const.
If the destroy clause appears on a depobj construct, destroy-var must refer to the same depend object as the depobj argument of the construct.
If the destroy clause appears on an interop construct destroy-var must refer to a variable of OpenMP interop type.
