* DESCRIPTION
|
| 41 |
|
|
*
|
| 42 |
|
|
* API routine to create an endpoint on the local node. If the port
|
| 43 |
|
|
* ID field is set to MCAPI_PORT_ANY, an endpoint will be created using
|
| 44 |
|
|
* the next available port in the system.
|
| 45 |
|
|
*
|
| 46 |
|
|
* INPUTS
|
| 47 |
|
|
*
|
| 48 |
|
|
* port_id The port ID of the endpoint, or MCAPI_PORT_ANY
|
| 49 |
|
|
* to create an endpoint with the next available
|
| 50 |
|
|
* port ID.
|
| 51 |
|
|
* *mcapi_status A pointer to memory that will be filled in
|
| 52 |
|
|
* with the status of the call.
|
| 53 |
|
|
*
|
| 54 |
|
|
* OUTPUTS
|
| 55 |
|
|
*
|
| 56 |
|
|
* The newly created endpoint.
