WDF_REL_TIMEOUT_IN_MS function (wdfcore.h)

[Applies to KMDF and UMDF]

The WDF_REL_TIMEOUT_IN_MS function converts a specified number of milliseconds to a relative time value.

Syntax

LONGLONG WDF_REL_TIMEOUT_IN_MS(
  [in] ULONGLONG Time
);

Parameters

[in] Time

The number of milliseconds to convert.

Return value

WDF_REL_TIMEOUT_IN_MS returns the relative time value, in system time units (100-nanosecond intervals), that represents the number of milliseconds that Time specifies.

Remarks

A relative time is a time value that is relative to the current system time. For example, if a caller passes a relative time value of five milliseconds to a function that accepts a time-out value, the function will time out five milliseconds after it is called.

Examples

The following code example starts a timer. The framework will call the timer's EvtTimerFunc callback function after ten milliseconds.

BOOLEAN inTimerQueue;

inTimerQueue = WdfTimerStart(
                             timerHandle,
                             WDF_REL_TIMEOUT_IN_MS(10)
                             );
