call Mac gcc -framework from CTypes how

$ cd /System/Library/Frameworks/
$ cd IOKit.framework/Versions/Current/
$ file IOKit
... Mach-O dynamically linked shared library ...
$ nm -m IOKit | grep IONotificationPortCreate
... (__TEXT,__text) external _IONotificationPortCreate
$

Looks like it will work.  Not named .dylib or .so, but correct `file`
type and relevant `nm -m` symbols.

Thanks all for help offline, especially Nlzero.com,
