Function

CFURLCreateWithBytes(_:_:_:_:_:)

Creates a CFURL object using a given character bytes.

Declaration

func CFURLCreateWithBytes(_ allocator: CFAllocator!, _ URLBytes: UnsafePointer<UInt8>!, _ length: CFIndex, _ encoding: CFStringEncoding, _ baseURL: CFURL!) -> CFURL!

Parameters

allocator

The allocator to use to allocate memory for the new CFURL object. Pass NULL or kCFAllocatorDefault to use the current default allocator.

URLBytes

The character bytes to convert into a CFURL object.

length

The number of bytes in URLBytes.

encoding

The string encoding of the URLBytes string. This encoding is also used to interpret percent escape sequences.

baseURL

The URL to which URLBytes is relative. Pass NULL if URLBytes contains an absolute URL or if you want to create a relative URL. If URLBytes contains an absolute URL, this parameter is ignored.

Return Value

A new CFURL object. Ownership follows the create rule. See The Create Rule.

Discussion

The specified string encoding will be used both to interpret URLBytes, and to interpret any percent-escapes within the string.
