Load application(s) using a config script or by path name.
If img_ds != L4DM_INVALID_DATASPACE then use the dataspace as binary/script else get the binary/script from the file provider denoted by fprov.
The loader interpretes the script and executes the included commands. See p_script for a description of the script syntax. If the file can be interpreted by the exec layer it is started directly. If not, it is interpreted as a config script.
| img_ds | Dataspace containing the script or binary. If this parameter is L4DM_INVALID_DATASPACE request file fname from file provider frov. | |
| fname | File name. If img_ds is used this parameter is only used for debugging. | |
| fprov | id of default file provider. | |
| flags | flags, set to L4LOADER_STOP if the load process should stop just before the task is really started. Use cont() to complete the load process. |
| task_ids | Task identifiers of started tasks. The maximum number of entries is MAX_TASK_ID. The first unused entry of that array contains L4_INVALID_ID. | |
| error_msg | Error message (helps debugging) |
| long l4loader::app::cont | ( | [in] l4_taskid_t | taskid | ) |
Continue task which was not completely started.
| taskid | ID of the task to continue. |
| long l4loader::app::kill | ( | [in] l4_taskid_t | task_id, | |
| [in] unsigned long | flags | |||
| ) |
Kill task.
The task must have been loaded by the Loader. This function is called by the event listener thread and must not called by any other thread.
| task_id | id of task to terminate | |
| flags | flags |
| long l4loader::app::dump | ( | [in] unsigned long | task_id, | |
| [in] unsigned long | flags | |||
| ) |
Dump task info.
Print out task info for the task to L4 debugging console. Only useful for debugging purposes.
| task_id | id of task to dump | |
| flags | flags |

| ) |
Get task info.
Return an L4 infopage for the specified task.
| task_id | id of task to get info from | |
| flags | flags |
| fname | application name | |
| l4env_page | l4env_infopage of process |
