* Some convenience macros to simplify programming of the
* /dev/sequencer interface
*
* 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.
