Function

CFBitVectorGetLastIndexOfBit(_:_:_:)

Locates the last occurrence of a certain bit value within a range of bits in a bit vector.

Declaration

func CFBitVectorGetLastIndexOfBit(_ bv: CFBitVector!, _ range: CFRange, _ value: CFBit) -> CFIndex

Parameters

bv

The bit vector to examine.

range

The range of bits in bv to search.

value

The bit value for which to search.

Return Value

The index of the last occurrence of value in the specified range of bv, or kCFNotFound if value is not present.
