AH
BX
0 (=RTX_SLEEP_TIME)
Sleep time in milliseconds in range 1 to 32767, inclusive. Note this 16 bit value is treated as signed.
Any non-positive values are translated within this API to 1 millisecond.
Return Value
Comments
DX = 0 success AX: 0
DX != 0 failure AX: contains error code
The RTX_WAKEUP_TASK API (service 0x06) can wake up a sleeping task before its sleep timer has
expired. In this case this API returns with error code -5 in AX.
The system maintains a "Task Wakeup Pending " flag for each task. This flag is set when
RTX_WAKEUP_TASK is called for a task which is not currently awaiting wakeup (i.e. when bit 7 in Task
State is zero). In the case where "Task Wakeup Pending " flag had been set, this RTX_SLEEP_TIME
API clears this flag and returns immediately with error code -5 in AX.

Developer Notes
A sleep call with BX parameter 1 millisecond sleeps for less than or equal to one millisecond. If a user needs a
minimum sleep time of 1 millisecond they must call RTX_SLEEP_TIME with value 2 in BX. In general with BX
sleep time specified to be N milliseconds, the resulting sleep time will range from N-1 milliseconds up to N
milliseconds (inclusive).
