Function

CFURLCreateFromFileSystemRepresentationRelativeToBase(_:_:_:_:_:)

Creates a CFURL object from a native character string path relative to a base URL.

Declaration

func CFURLCreateFromFileSystemRepresentationRelativeToBase(_ allocator: CFAllocator!, _ buffer: UnsafePointer<UInt8>!, _ bufLen: CFIndex, _ isDirectory: Bool, _ 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.

buffer

The character bytes to convert into a CFURL object. This should be the path as you would use in POSIX function calls.

bufLen

The number of bytes in the buffer.

isDirectory

A Boolean value that specifies whether the string is treated as a directory path when resolving against relative path components. Pass true if the pathname indicates a directory, false otherwise.

baseURL

The URL against which to resolve the path.

Return Value

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

Discussion

This function takes a path name in the form of a native character string, resolves it against a base URL, and returns a new CFURL object containing the result.
