Semantics

The is_device_ptr clause indicates that its list items are device pointers. Support for device pointers created outside of OpenMP, speciﬁcally outside of any OpenMP mechanism that returns a device pointer, is implementation deﬁned.

If the is_device_ptr clause is speciﬁed on a target construct, each list item privatized inside the construct and the new list item is initialized to the device address to which the original list item refers.

If the is_device_ptr clause is speciﬁed on a target construct, if any list item is not of type C_PTR, the behavior is as if the list item appeared in a has_device_addr clause. Support for such list items in an is_device_ptr clause is deprecated.

Restrictions

Restrictions to the is_device_ptr clause are as follows:

Each list item must be a valid device pointer for the device data environment.

∙ Each list item must have a type of pointer or array.

∙ Each list item must have a type of pointer, array, reference to pointer or reference to array.

∙ Each list item must be of type C_PTR unless the clause appears on a target directive; the use of list items on the target directive that are not of type C_PTR has been deprecated.
