Creates a new authorization reference and provides an option to authorize or preauthorize rights.
- macOS 10.0+
A pointer to a set of authorization rights you create. Pass
NULLif the application requires no rights at this time.
Authorizationstructure used when authorizing or preauthorizing rights.
Not used in OS X v10.2 and earlier.
In macOS 10.3 and later, you can pass icon or prompt data to be used in the authentication dialog box.
In macOS 10.4 and later, you can also pass a user name and password in order to authorize a user without user interaction. Possible values for this parameter are listed in
.framework/Headers/Authorization Tags .h
The data passed in this parameter is not stored in the authorization reference; it is used only during authorization. If you are not passing any data in this parameter, pass the constant

destroyflag to prevent the Security Server from preserving the rights obtained during this call.
A pointer to an authorization reference. On return, this parameter refers to the authorization session the Security Server creates. Pass
NULLif you require a function result but no authorization reference.
A result code. See Authorization Services Result Codes.
The primary purpose of this function is to create the opaque authorization reference structure associated with the authorization reference. You use the authorization reference in other authorization functions.
You can use this function to authorize all or partial rights. Authorizing rights with this function is most useful for applications that require a one-time authorization. By passing
NULL to the
authorization parameter, the Security Server attempts to authorize the requested rights and returns the appropriate result code without actually granting the rights. If you are not going to call any other authorization functions, use this method to determine if a user has authorization without granting any rights.
You can also use this function to preauthorize rights by specifying the
pre mask. Preauthorization is most useful when a right has a zero timeout. For example, you can preauthorize in the application and if it succeeds, call the helper tool and request authorization. This eliminates calling the helper tool if the user cannot later authorize the specified rights.
When your application no longer needs the authorization reference, use the function
Authorization to free the memory associated with it.
