+ * @param bufferSize  Capacity of `buffer` in bytes.
+ * @param args  Array of typed arguments; may be NULL when `argCount` is 0.
+ * @param argCount  Number of elements in `args`.
+ * @return OK on success, error if the message is not found, an argument type
+ *         mismatches the specifier, or the buffer would overflow.
