CFDictionaryGetCount

CFDictionaryGetCount is a function in the Core Foundation framework of Apple's operating systems. Its primary purpose is to retrieve the number of key-value pairs currently stored within a given Core Foundation dictionary. The function takes a single argument: a reference to the CFDictionary object whose size you wish to determine. It returns a CFIndex value, which is a signed integer type capable of holding the size of any object. This function is useful for various operations, such as allocating memory for processing dictionary elements, checking if a dictionary is empty, or performing iterative tasks where the number of elements is needed beforehand. It's a straightforward and efficient way to ascertain the current occupancy of a CFDictionary. The returned count reflects the number of unique keys present in the dictionary.
