This works nicely with a minimum resolution of 1 ms in XP. The
first call of timeSetEvent() however takes a while (5-7 ms on
on my system) since a thread is created first.

Hello Paul,
What about the assembler pause opcode? I think it is introduced starting
pentium 4. You could do the delay loop in asm and insert pause's to
decrease the cpu load.

This is a delay of max a few microseconds and it is working this way

Not exacly. If you use SendMessage to a message pump for a window
created in the same thread contextt then it is just a function call. If
other thread context then it will block until the thread has timesli

Is it true that under Linux one could specify delays in microsecs
instead of millisecs for Windows??

I know, but since there are a lot of very short instructions to send, this

You can implement a blocking 2ms delay using QueryPerformanceCounter
which returns a 64-bit counter, and QueryPerformanceFrequency which gives
you ticks per second for the counter.

Hello Paul,
You could do very small delays by posting a message to a custom message
handler. You cannot measure the delay, but it is not depending the
timeslice like with the other delay's or a TTimer.
