The qualifier allows programmer to directly control how pointers are signed when they are stored in a particular variable. The qualifier takes three arguments: the signing key, a flag specifying whether address discrimination should be used, and a non-negative integer that is used for additional discrimination. ``` typedef void (*my_callback)(const void*); my_callback __ptrauth(ptrauth_key_process_dependent_code, 1, 0xe27a) callback; ``` Co-Authored-By: John McCall rjmccall@apple.com
