GetCaretTime
GetCaretTime Obtain insertion-point cursor blink interval
#include <Events.h> Event Manager
returns the interval between caret blinks, in ticks
GetCaretTime returns the amount of time, in 1/60-th second ( 16.66 ms)
ticks, between blinks of the text-editing insertion point caret (normally a
vertical bar).
Returns: a 32-bit long; the caret blink interval, as set by the user via the
Control Panel DA.

Notes: Another way to access this information is by reading the global variable
CaretTime (at 0x02F4).
If you use TextEdit, the caret blinking is automatic (if you call TEIdle
appropriately). Otherwise, you should check the elapsed ticks at each pass
through your main event loop, and toggle the display on or off as each
CaretTime-tick interval elapses.
