So I ALMOST got it.
The second argument is defined as unsigned int 0xFFFFFFFF
But when I try to make one in python, it converts to a long, and I
get an error.
import objc
from Foundation import NSBundle
from time import sleep
bundle = NSBundle.bundleWithPath_(
objc.pathForFramework('ApplicationServices.framework'))
objc.loadBundleFunctions(NSBundle.bundleWithPath_(
objc.pathForFramework('ApplicationServices.framework')),
globals(), [('CGEventSourceSecondsSinceLastEventType', 'iii')])
print int('0xFFFFFFFF', 16)
a = int(4294967295)
print type(a)
# This should work, even though I don't get the 'i' or 'ii' for in/
outputs
print CGEventSourceSecondsSinceLastEventType(0, a) / 1000000000.0
