kCFNumberIntType

kCFNumberIntType is a constant in the Core Foundation framework of Apple's macOS and iOS operating systems. It is used to specify the type of a CFNumber object as a 32-bit signed integer. CFNumber is a Core Foundation data type that represents a numeric value, and it can store various types of numbers, including integers, floating-point numbers, and Booleans. The kCFNumberIntType constant is one of several type identifiers that can be used to create a CFNumber object with a specific numeric type. When a CFNumber object is created with the kCFNumberIntType constant, it is initialized to store a 32-bit signed integer value. This constant is particularly useful when working with Core Foundation APIs that require a CFNumber object with a specific numeric type. It is important to note that the size of an integer in Core Foundation is platform-dependent, and the kCFNumberIntType constant represents a 32-bit signed integer on 32-bit platforms and a 64-bit signed integer on 64-bit platforms. Additionally, Core Foundation provides other type identifiers for different numeric types, such as kCFNumberFloatType for 32-bit floating-point numbers and kCFNumberDoubleType for 64-bit floating-point numbers.
