# CFDictionaryGetKeysAndValues(_:_:_:) Fills two buffers with the keys and values from a dictionary. ``` func CFDictionaryGetKeysAndValues(_ theDict: CFDictionary!, _ keys: UnsafeMutablePointer!, _ values: UnsafeMutablePointer!) ``` ## Parameters `theDict` The dictionary to examine. `keys` A C array of pointer-sized values that, on return, is filled with keys from the `theDict`. The keys and values C arrays are parallel to each other (that is, the items at the same indices form a key-value pair from the dictionary). This value must be a valid pointer to a C array of the appropriate type and size (that is, a size equal to the count of `theDict`), or `NULL` if the keys are not required. If the keys are Core Foundation objects, ownership follows the [The Get Rule](https://developer.apple.com/library/archive/documentation/CoreFoundation/Conceptual/CFMemoryMgmt/Concepts/Ownership.html#//apple_ref/doc/uid/20001148-SW1). `values` A C array of pointer-sized values that, on return, is filled with values from the `theDict`. The keys and values C arrays are parallel to each other (that is, the items at the same indices form a key-value pair from the dictionary). This value must be a valid pointer to a C array of the appropriate type and size (that is, a size equal to the count of `theDict`), or `NULL` if the values are not required. If the values are Core Foundation objects, ownership follows the [The Get Rule](https://developer.apple.com/library/archive/documentation/CoreFoundation/Conceptual/CFMemoryMgmt/Concepts/Ownership.html#//apple_ref/doc/uid/20001148-SW1). ## Discussion --- Copyright © 2026 Apple Inc.
