Thank You I found the sleep procedure.... Thank you for explaining that it was looking for a pointer, that was helpful. A little cutting and pasting and now I have 3 more ways to sleep... Sleep_S will probably be sufficient and is the most flexible, because if you have 1,000,000,000 seconds you don't need precision down to 100nS.. but you have it anyway, you could specify 1000000000.0000001 seconds and it would work... it comes out to 10000000000000001 intervals... I'm not going to wait over 31 years to test it though :)
Thanks for the help everyone, now I can adjust my delay from 36uS for baudrates of 250000 all the way to 30mS for a baudrate of 300. I know sleep isn't exact, it's more of a minimum and then you need to also wait for the processor to get back to you, but I think it will be close enough without excessive delays. I posted it on github if anyone happens across this doing a search they can find it here: https://github.com/Zaaphod/FPC-Delay >You need to declare a LargeInteger and pass the pointer to it to NtDelayExecution(). LargeInteger itself is declared as a case-record >consisting of two 32-bit values (LowPart and HighPart) and a 64-bit value (QuadPart). Best is you assign your value to QuadPart, as > that sets the record in one go. >Oh and I forgot to mention that you need to use a negative value for relative sleeps (otherwise you'll wait until that time from the >system start on has passed, so "1" would be a no-op basically ;) ) >For an example see the implementation of Sleep in the SysUtils unit of the NativeNT target: rtl/nativent/sysutils.pp (near the end of the file) >Regards, >Sven _______________________________________________ fpc-pascal maillist - fpc-pascal@lists.freepascal.org http://lists.freepascal.org/cgi-bin/mailman/listinfo/fpc-pascal
