Function Documentation

static nsresult GetDevCapRangeUpper ( sbIDevCapRange *  aRange, PRInt32  aTarget, PRInt32 *  _retval  )

static

Get a value in a sbIDevCapRange that is no smaller than the given target value, unless it's larger than the maximum (in which case return that)

Parameters

aRange	the range to look at
aTarget	the value we want

Returns

a value in range that's no smaller than the target; or, the maximum in the range and throw NS_SUCCESS_LOSS_OF_INSIGNIFICANT_DATA
