Detailed Documentation
~~~~~~~~~~~~~~~~~~~~~~

Primitive descriptor query specification.

In general, queries are not used with the C++ API because most queries are implemented as class members.

See :ref:`dnnl_query_t <doxid-group__dnnl__api__primitives__common_1ga9e5235563cf7cfc10fa89f415de98059>` for more information.
