GetLAContext

Constructs a local authentication context.

Declaration

int (*)(struct __OpaqueAuthorizationEngine *, const void **) GetLAContext;

inEngine:
An opaque handle that’s passed to your plug-in when the authorization engine calls your Mechanismcreate function.
outValue:
A pointer the function uses to return the Lacontext instance.

If a PIN is available, you can use the context for token operations that would normally require a PIN.

You can also use this context for keychain item accesses, for example using the SecItemCopyMatching(_:_:) function, that include the kSecUseAuthenticationContext key in the query dictionary.

The caller owns the returned context and is responsible for releasing it.
