Task Template List

The task template list, which is a list of task templates ( TASK_TEMPLATE_STRUCT), defines an initial set of templates. Tasks can be created on the processor by using this list. At initialization, MQX Lite creates one instance of each task, whose template defines it as an autostart task. In addition, while an application is running, it can create other tasks using a task template that the task template list defines. Dynamic task creation is not allowed in MQX Lite. All task resources must be pre-allocated statically at compile time. The end of the task template list is marked by a zero-filled task template.
