sleep in microsecond granularity in linux

[Leo Prasath]

Hi there,

Is it possible to sleep in granularity of microseconds ?
>From what i know, there is msleep() which can sleep in milliseconds
and there is udelay() which busy waits for time in microsecond
granularity.
But I need to sleep ( not busy wait ) for granularity of microseconds ...

Is there a way to code a new API in linux kernel to allow this ? For
example using interrupts ..
Or is there a way to some external hardware timer cards that issue
interrupts after certain usecs ?

Any help / pointers/ tips will be very appreciated.

Thanks,
-Leo
