The UniCharArrayHandle type is a handle that points to the beginning of a text buffer. Note that ATSUI expects the buffer to contain Unicode text. Your application is responsible for allocating the memory associated with this handle. ATSUI functions that need to access text referenced by this handle will return the handle to its original state (locked or unlocked) upon function completion. You use the UniCharArrayHandle type with the functions ATSUCreateTextLayoutWithTextHandle and ATSUSetTextHandleLocation.
typedef UniCharArrayPtr * UniCharArrayHandle;
