27    Syntax                                   Description
28    ======================================== ========================================================================
29    sendmsg(<*type*>)                        A message identified by its *type*.
30    sendmsg(<*type*>, <*op*>)                A message identified by its *type* and *operation*.
31    sendmsg(<*type*>, <*op*>, <*stream*>)    A message identified by its *type* and *operation* with a stream *id*.
32    ======================================== ========================================================================
33
34*Type* may be specified using message *name* or message *id*.
35
36*Op* may be specified using operation *name* or operation *id*.
37
38Stream *id* is an integer in the range 0..3.
39
40Message *id*, operation *id* and stream *id* must be specified as positive :ref:`integer numbers<amdgpu_synid_integer_number>`.
