|
* @param[in] scif_controller the handle to the framework controller object
|
|
* for which to build an IO request.
|
|
* @param[in] scif_remote_device This parameter specifies the framework
|
|
* remote device with which this task request is to be associated.
|
|
* @param[in] io_tag This parameter specifies the IO tag to be associated
|
|
* with this request. If SCI_CONTROLLER_INVALID_IO_TAG is
|
|
* passed, then a copy of the request is built internally. The
|
|
* request will be copied into the actual controller request
|
|
* memory when the IO tag is allocated internally during the
|
|
* scif_controller_start_task() method.
|
|
* @param[in] user_task_request_object This parameter specifies the user
|
|
* task request to be utilized during task construction. This task
|
|
* pointer will become the associated object for the framework
|
|
* task request object.
|
|
* @param[in] task_request_memory This parameter specifies the memory
|
|
* to be utilized in the construction of the framework task request.
|
|
* @param[in] scif_task_request This parameter specifies the handle to be
|
|
* utilized for all further interactions with this task request
|
|
* object.
|
|
*
|
|
* @return Indicate if the controller successfully built the task request.
|

* @retval SCI_SUCCESS This value is returned if the task request was
