Primitive descriptor query specification.

For generic function dnnl_primitive_desc_query(), the type of result must agree with the queried argument. The correspondence table:

Query kind	Type of query result
dnnl_query_*_engine	dnnl_engine_t *
dnnl_query_primitive_kind	dnnl_primitive_kind_t *
dnnl_query_*_s32	int *
dnnl_query_*_s64	dnnl_dim_t * (same as int64_t )
dnnl_query_*_f32	float *
dnnl_query_*_f64	double *
dnnl_query_*_str	const char **
dnnl_query_*_md	const_dnnl_memory_desc_t *

dnnl_query_sparse_encoding	#dnnl_sparse_encoding_t *

NOTE:

Rule of thumb: all opaque types and structures are returned by reference. All numbers are returned by value.

WARNING:

All returned references point to constant objects and are valid only during the lifetime of the queried primitive descriptor. Returned objects must not be destroyed by the user. If you need to keep the object longer than the lifetime of the queried primitive descriptor, use dnnl_primitive_desc_clone() to make a copy.
