+// Port of pflib/external/openal/CAException.h (Apple Core Audio utility class, Playground SDK 4.0): the exception
+// type that carries an OSStatus error code. Header-only in both builds: the constructor and the empty, non-virtual
+// destructor are inline, so the class has no vtable; it is just mError (size 4).
+//
+// Game code: the game keeps one out-of-line copy of the (inline) destructor, game @0x001926c4 (D1, empty); the
+// constructor is inlined at every throw site (a throw site allocates the exception, stores the error and throws
+// with this destructor as the cleanup). sdk @0x18c4 (constructor) / @0x18d4 (destructor) in
+// parity-out/sdk/dbgobj/CAMutex.o and sdk @0x1e38 / @0x1e48 in CAGuard.o.
+//
+// CATry / CACatch / CASwallowException are kept as declared (the ported code does not use them so far).
