STREAMS provides the StrmConvertCentisecondsToRelativeTimeout function to conveniently convert timeouts expressed in UNIX clock ticks to Windows NT relative timeouts. Such conversion is useful when timeout calls (Section B.3.4) are being converted into StrmWaitFor* calls (Section B.3.6).
LARGE_INTEGER StrmConvertCentisecondsToRelativeTimeout( IN ULONG Centiseconds );
