Synopsis

 unsigned short getTaskState(int id)

Parameter

task : Pointer to the task function

Description

This function returns the current enable state of the specified task. The task enable states are the same as specified by createTask(). The value TASK_DISABLE is returned for both valid, disabled tasks, and when the task identifier is invalid.

Return Value

Current task enable state:

TASK_ENABLE The task is enabled and will be run at the specified intervals.
TASK_DISABLE The task is disabled and will not be run.
TASK_RUN_ONCE The task is enabled to run once and then will become disabled after running.
Number ‘n’ The task is enabled to run and will run ‘n’ times. After the ‘n’th execution, the task becomes disabled.

Conforming To

The Task Management Functions are specific to ChipKit and exceed the Arduino 1.6.x specification.

Example

 int blink_id;
 short task_state;
 unsigned long blink_var;
 void blink_task(int id, void * tptr) {
   digitalWrite(led, !digitalRead(led); // Toggle pin state
 }
 void setup() {
   pinMode(led, OUTPUT);
   blink_id = createTask(blink_task, 200, TASK_ENABLE, &blink_var);
   task_state = getTaskState( blink_id);
 }
