hil_task_delete_all

Deletes all tasks associated with a card.

Description

The hil_task_delete_all function deletes all tasks that are associated with the given card. Any tasks that are running, will be stopped prior to being deleted. All task handles associated with the card become invalid and may no longer be used.

hil_task_delete_all(t_card card);
    

Parameters

t_card card

A handle to the board, as returned by hil_open.

Return value

The return value is the number of tasks that were deleted successfully. This number may be less than the number of tasks if not all tasks could be deleted successfully. A negative error code may also be returned if the function is not supported or the card handle is invalid. Error codes are defined in quanser_errors.h. A suitable error message may be retrieved using msg_get_error_message.
