    What does 'sleep' function do?

    With reference to my previous thread on copying USB drive



    http://www.vbforums.com/showthread.php?t=503894

    Code:
    Private Declare Sub Sleep Lib "kernel32" (ByVal dwMilliseconds As Long)
    I was told that the 'sleep' function pauses the application for specified time interval. (May not necessarily give time to other processes to run simultaneously ).

    Is it true?


    So what is the difference between 'sleep' and this loop?

    Code:
    Dim date1 As Date
date1 = Now
While (DateDiff("s", date1, Now) < 5)
Wend

    My main concern is to let my application give some breathing time to other processes while copying folders of several gig in size
