Core Foundation #2

Closed lowne closed 7 years ago

lowne commented 7 years ago

How to use APIs that require CFStrings? e.g.

c.load'CoreFoundation'
c.load'ApplicationServices.HIServices'
c.AXUIElementCopyAttributeValue(sw,c.kAXFocusedUIElementAttribute,elm)

> bad argument #2 to 'func' (cannot convert 'string' to 'struct __CFString *')

I tried mucking around with c.addfunction('AXUIElementCopyAttributeValue',{'^{__AXUIElement=}','@','^^v'},false) but then the call appears to do nothing...
