CFGetTypeID | Header: CFBase.h |
Obtains the unique identifier of the opaque type to which a Core Foundation object belongs.
CFTypeID CFGetTypeID ( CFTypeRef cf );
A generic reference of type CFTypeRef. Pass a reference to any Core Foundation object whose type ID you want to obtain.
A value of type CFTypeID that identifies the opaque type of a Core Foundation object.
This function returns a value that uniquely identifies the opaque type of any Core Foundation object. You can compare this value with the known CFTypeID identifier obtained with a "GetTypeID" function specific to a type, for example CFDateGetTypeID. These values might change from release to release or platform to platform.
