Delay() inside "While ProgramRunning..."-Loop?

[Lebostein]

Should a delay be included here? I have the whole thing running in a thread....

Code: Select all

While ProgramRunning(programID)
  ; Delay() ???
  If AvailableProgramOutput(programID)
    output$ + ReadProgramString(programID) + #CRLF$
  EndIf
Wend

[STARGÅTE]

Yes, a Delay(0) is enough.

Code: Select all

While ProgramRunning(programID)
  If AvailableProgramOutput(programID)
    output$ + ReadProgramString(programID) + #CRLF$
  Else
    Delay(0)
  EndIf
Wend

Please ignore my ignorance, but what does a Delay(0) do?

It instructs the scheduler of your operating system to use the CPU for an other thread/process until the scheduler decides to give your thread attention again.

It instructs the scheduler of your operating system to use the CPU for an other thread/process until the scheduler decides to give your thread attention again.

Is that not only true for Windows?
