Re: USleep -- RPG400-L

I would suggest adding a timer and display the times. I doubt debug would affect this but it has some very odd effects.

When I tried sleep and measured it - which would have been back in V5R2 timeframe - I used it in a loop so the time differences were big enough to measure.

Just try it in a loop of (say) 10x and display the start and end times. You’ll need to run multiple times to get a meaningful result. Also prime the input value with different values and look for the difference. The time delay will not be precise - you’re on a multi user machine which will have an effect.

I run it in debug.

The examples I have seen have the value defined as 10U 0.
I did try as integer with no change.

The return value should be an integer not a an unsigned I believe but that would not make a difference.

You don’t appear to have any timing mechanism in the program so how do you know if it is sleeping or not?

Hi All,

I am testing the following code:

H Option(*SrcStmt : *NoDebugIO)
H DftActGrp(*No) ActGrp(*Caller) BndDir('QC2LE')

D MicroSec S 10U 0
D StrStamp S Z Inz(Z'2016-07-05-18.55.04.377000')
D EndStamp S Z Inz(Z'2016-07-05-18.55.01.110000')

D USleep PR 10U 0 ExtProc('usleep')
D 10U 0 Value

/Free

MicroSec = %Diff(StrStamp : EndStamp : *MSeconds);

USleep(MicroSec);

*InLr = '1';

The MicroSec gets loaded with 3267000.

When it executes the USleep it should delay 3267000 micro seconds (3.267000 seconds).

There is NO delay at all. What am I not doing correctly?

I am currently on 5.4 (I know, working on it)
