| * |
| * The type of assignment depends on the dprc_res_req options, as follows: |
| * - DPRC_RES_REQ_OPT_EXPLICIT: indicates that assigned resources should have |
| * the explicit base ID specified at the id_base_align field of res_req. |
| * - DPRC_RES_REQ_OPT_ALIGNED: indicates that the assigned resources should be |
| * aligned to the value given at id_base_align field of res_req. |
| * - DPRC_RES_REQ_OPT_PLUGGED: Relevant only for object assignment, |
| * and indicates that the object must be set to the plugged state. |
| * |
| * A container may use this function with its own ID in order to change a |

| * |
