Comment (by dawuud):

 Currently I have a failed attempt at creating this CFArray of CFString`s;
 running it results in a segmentation fault... however the VM i'm using
 won't write a core file. What to do?

 {{{
 (virtenv-objc) xcloud114:~ Xcloud$ python test.py
 Segmentation fault: 11
 }}}

 {{{
 #!/usr/bin/env python

 import ctypes
 from ctypes import POINTER, byref, create_string_buffer, addressof
 from ctypes import cdll, c_void_p
 from ctypes.util import find_library

 # kCFStringEncodingUTF8
 UTF8 = 134217984
 # kCFAllocatorDefault
 CF_DEFAULT_ALLOCATOR = None

 core_services = cdll.LoadLibrary(find_library('CoreServices'))
 core_foundation = cdll.LoadLibrary(find_library('CoreFoundation'))

 def PyStringToCFString(pystring):
     return core_foundation.CFStringCreateWithCString(CF_DEFAULT_ALLOCATOR,
                                   pystring.encode('utf8'),
                                   UTF8)

 my_cfarray = core_foundation.CFArrayCreate(None, None, 0,
 ctypes.c_int.in_dll(core_services, "kCFTypeArrayCallBacks"))
 my_cfstr = PyStringToCFString("/Users/Xcloud/magic-folder")

 core_foundation.CFArrayAppendValue(my_cfarray, my_cfstr)

 }}}
