\section{C++ Reference in Data-Sharing Clauses}

C++ reference types are allowed in data-sharing attribute clauses as of OpenMP 4.5, except
|
|
for the \kcode{threadprivate}, \kcode{copyin} and \kcode{copyprivate} clauses.
|
|
(See the \docref{Data-Sharing Attribute Clauses} section of the 4.5 OpenMP specification.)
|
|
When a variable with C++ reference type is privatized, the object the reference refers to is privatized in addition to the reference itself.
|
|
The following example shows the use of reference types in data-sharing clauses in the usual way.
|
|
Additionally it shows how the data-sharing of formal arguments with a C++ reference type on an orphaned task generating construct is determined implicitly. (See the \docref{Data-sharing Attribute Rules for Variables Referenced in a Construct} section of the 4.5 OpenMP specification.)
