Function

CFURLCreateAbsoluteURLWithBytes

Creates a new CFURL object by resolving the relative portion of a URL, specified as bytes, against its given base URL.

Declaration

CFURLRef CFURLCreateAbsoluteURLWithBytes(CFAllocatorRef alloc, const UInt8 *relativeURLBytes, CFIndex length, CFStringEncoding encoding, CFURLRef baseURL, Boolean useCompatibilityMode);

Parameters

allocator

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

relativeURLBytes

The character bytes that represent a relative URL to convert into a CFURL object.

length

The number of bytes in relativeURLBytes.

encoding

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

baseURL

The URL to which relativeURLBytes is relative.

useCompatibilityMode

If true, the rules historically used on the web are used to resolve the string specified by the relativeURLBytes parameter against baseURL. These rules are generally listed in the RFC as optional or alternate interpretations. Otherwise, the strict rules from the RFC are used.

Return Value

A new CFURL object, or NULL if relativeURLBytes cannot be made absolute. Ownership follows the create rule. See The Create Rule.

Discussion

This function interprets the provided bytes using the specified string encoding to create the relative portion of the URL’s address.
