*   FUNCTION

*

*       get_endpoint

*

*   DESCRIPTION

*

*       Retrieves the endpoint identifier associated with a specific node

*       ID and port ID.

*

*   INPUTS

*

*       node_id                 The unique ID of the node on which the target

*                               endpoint resides.

*       port_id                 The port ID of the target endpoint.

*       *mcapi_status           A pointer to memory that will be filled in

*                               with the status of the call.

*       timeout                 The amount of time to block for the operation

*                               to complete.

*

*   OUTPUTS

*

*       The endpoint identifier associated with the node ID / port ID

*       combination.
