I have a function that must be executed continously over a period of one second.

I've previously achieved this with the following code:

st = GetTickCount() + 1000
do while GetTickCount() < st
TMValidSession(session_handle)
enddo

(The function GetTickCount() is a KERNEL32.DLL API Call, and the
function TMValidSession() is an API-call to a DLL that communicates
with a network of temperature sensors)

The problem with the above code, is the amount of CPU-power it consumes. This causes problems for other applications running
on my system.

I've been told that this C-code is more CPU-friendly:

for (i = 0; i < 5; i++)
{
   TMValidSession(session_handle);
   Sleep(200);
}

How can I write function similar to Sleep(), in FoxPro?
