Accesses the set of authorizations of a user.
Security Library (libc.a)
The GetUserAuths subroutine returns the list of authorizations associated with the real user ID and group set of the process. By default, the ALL authorization is returned for the root user.
If successful, the GetUserAuths subroutine returns a list of authorizations associated with the user. The format of the list is a series of concatenated strings, each null-terminated. A null string terminates the list. Otherwise, a null pointer is returned and the errno global variable is set to indicate the error.
