Functions
XPlmi_TaskNode *	XPlmi_TaskCreate (TaskPriority_t Priority, int(*Handler)(void *Arg), void *PrivData)
	This function creates the task and initializes its fields with the user parameters. More...
XPlmi_TaskNode *	XPlmi_GetTaskInstance (int(*Handler)(void *Arg), const void *PrivData, const u32 IntrId)
	This function returns the instance of the task with matching handler and private data or with matching interrupt id. More...
void	XPlmi_TaskTriggerNow (XPlmi_TaskNode *Task)
	This function adds the task to the task queue so that it can be triggered based on its priority. More...
void	XPlmi_TaskInit (void)
	This function initializes the task queues list. More...
void	XPlmi_TaskDispatchLoop (void)
	This function will be checking for tasks in the queue based on the priority. More...
