+ * IMPORTANT NOTE: Apple iOS and OS X
+ *
+ * Previous versions of this header file defined the xdrproc_t prototype as
+ * typedef bool_t (*xdrproc_t)(XDR *, ...);
+ *
+ * This prototype is incorrect. One may not use a varargs function pointer
+ * in place of pointer to a function with positional parameters.
+ * This mistake has been masked by the fact that clients of this API would
+ * generally cast their xdr functions as (xdrproc_t), and thus silence compiler
+ * warnings. The code worked because the ABI for varargs routines that pass a
+ * small number of arguments has been the same as the ABI for routines with a
+ * few positional parameters. However, if the ABI differs this will cause the
+ * compiled code to fail.
+ *
+ * Historically, some client xdr routines expected three parameters. This
+ * does not seem to be the case in more recent code, but we have decided to
+ * retain this definition in the XDR library in case some legacy code still
+ * expects three parameters. The library will pass zero as the third
+ * parameter. Routines that expect two parameters will work correctly.
+ *
+ * If your client-side xdr routine is of the form:
+ * bool_t xdr_my_datatype(XDR *, void *);
+ * and you pass your function pointer to routines like xdr_pointer or
+ * xdr_reference using "(xdrproc_t)xdr_my_datatype", then your code will
+ * compile and run correctly. If your code invokes an xdrproc_t callback,
+ * it must be modified to pass a third parameter, which may simply be zero.
