Do you find some better place for:
void seqbuf_dump(void); /* This function must be provided by programs */
extern int OSS_init(int seqfd, int buflen);
extern void OSS_seqbuf_dump(int fd, unsigned char *buf, int buflen);
extern void OSS_seq_advbuf(int len, int fd, unsigned char *buf, int buflen);
extern void OSS_seq_needbuf(int len, int fd, unsigned char *buf, int buflen);
extern void OSS_patch_caching(int dev, int chn, int patch,
int fd, unsigned char *buf, int buflen);
extern void OSS_drum_caching(int dev, int chn, int patch,
int fd, unsigned char *buf, int buflen);
extern void OSS_write_patch(int fd, unsigned char *buf, int len);
extern int OSS_write_patch2(int fd, unsigned char *buf, int len);
..
#ifdef OSSLIB
# define SEQ_USE_EXTBUF() \
extern unsigned char *_seqbuf; \
extern int _seqbuflen;extern int _seqbufptr
# define SEQ_DEFINEBUF(len) SEQ_USE_EXTBUF();static int
_requested_seqbuflen=len
# define _SEQ_ADVBUF(len) OSS_seq_advbuf(len, seqfd, _seqbuf, _seqbuflen)
# define _SEQ_NEEDBUF(len) OSS_seq_needbuf(len, seqfd, _seqbuf, _seqbuflen)
# define SEQ_DUMPBUF() OSS_seqbuf_dump(seqfd, _seqbuf, _seqbuflen)
# define SEQ_LOAD_GMINSTR(dev, instr) \
OSS_patch_caching(dev, -1, instr, seqfd, _seqbuf, _seqbuflen)
# define SEQ_LOAD_GMDRUM(dev, drum) \
OSS_drum_caching(dev, -1, drum, seqfd, _seqbuf, _seqbuflen)
#else /* !OSSLIB */
# define SEQ_LOAD_GMINSTR(dev, instr)
# define SEQ_LOAD_GMDRUM(dev, drum)
# define SEQ_USE_EXTBUF() \
extern unsigned char _seqbuf[]; \
extern int _seqbuflen;extern int _seqbufptr
..
what are your plans.
