* Some convenience macros to simplify programming of the

- * These macros define the API which should be used when possible.
+ * This is a legacy interface for applications written against
+ * the OSSlib-3.8 style interface. It is no longer possible
+ * to actually link against OSSlib with this header, but we
+ * still provide these macros for programs using them.
+ *
+ * If you want to use OSSlib, it is recommended that you get
+ * the GPL version of OSS-4.x and build against that version
+ * of the header.
+ *
+ * We redefine the extern keyword so that make headers_check
+ * does not complain about SEQ_USE_EXTBUF.
