; * 0. If the specified delay is greater than 0 then, a context switch will result.
; *
; * Arguments : ticks is the time delay that the task will be suspended in number of clock 'ticks'.
; * Note that by specifying 0, the task will not be delayed.

; * DELAY TASK FOR SPECIFIED TIME
; *
; * Description: This function is called to delay execution of the currently running task until some time
; * expires. This call allows you to specify the delay time in HOURS, MINUTES, SECONDS and
; * MILLISECONDS instead of ticks.
; *
; * Arguments : hours specifies the number of hours that the task will be delayed (max. is 255)
; * minutes specifies the number of minutes (max. 59)
; * seconds specifies the number of seconds (max. 59)
; * milli specifies the number of milliseconds (max. 999)
; *
; * Returns : OS_NO_ERR
; * OS_TIME_INVALID_MINUTES
; * OS_TIME_INVALID_SECONDS
; * OS_TIME_INVALID_MS
; * OS_TIME_ZERO_DLY
; *
; * Note(s) : The resolution on the milliseconds depends on the tick rate. For example, you can't do
; * a 10 mS delay if the ticker interrupts every 100 mS. In this case, the delay would be
; * set to 0. The actual delay is rounded to the nearest tick.
