Detailed Description

Enumeration Type Documentation

enum mkldnn_query_t

Primitive descriptor query specification

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

Query | type of result

mkldnn_query_engine | mkldnn_engine_t * mkldnn_query_scratchpad_engine | mkldnn_engine_t * mkldnn_query_primitive_kind | mkldnn_primitive_kind_t * *_s32 | int * *_s64 | mkldnn_dim_t * (same as int64_t *) *_f64 | double * *_str | const char ** mkldnn_query_op_d | const_mkldnn_op_desc_t * *_md | const mkldnn_memory_desc_t ** *_${op}_d | const mkldnn_${op}_desc_t ** *_pd | const_mkldnn_primitive_desc_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 mkldnn_primitive_desc_clone() to make a copy.
