129 The hold reference count is otherwise modeled after OpenACC's
130 structured reference count.  For example, calling ``acc_unmap_data``,
132 the structured reference count is not zero.
135 semantics for selecting OpenACC reference counts differently than for
136 selecting OpenMP reference counts, the implementation is the same at
137 the runtime level.  That is, OpenACC's dynamic reference count is
138 OpenMP's dynamic reference count, and OpenACC's structured reference
139 count is our OpenMP hold reference count extension.
