39
*
40
*   DESCRIPTION
41
*
42
*       Non-blocking API routine to retrieve the endpoint identifier
43
*       associated with a specific node ID and port ID.
44
*
45
*   INPUTS
46
*
47
*       node_id                 The unique ID of the node on which the target
48
*                               endpoint resides.
49
*       port_id                 The port ID of the target endpoint.
50
*       *endpoint               A pointer to memory that will be filled in
51
*                               with the endpoint identifier associated
52
*                               with the node ID / port ID combination.
53
*       *request                A pointer to memory that will be filled in
54
*                               with data relevant to the operation, so the
55
*                               status of the operation can later be checked.
56
*       *mcapi_status           A pointer to memory that will be filled in
57
*                               with the status of the call.
58
*
59
*   OUTPUTS
60
*
61
*       None.
