Macros

#define SND_SEQ_EVENT_LENGTH_FIXED

fixed event size

#define SND_SEQ_EVENT_LENGTH_MASK

mask for event length bits

#define SND_SEQ_EVENT_LENGTH_VARIABLE

variable event size

#define SND_SEQ_EVENT_LENGTH_VARUSR

variable event size - user memory space

#define SND_SEQ_PRIORITY_HIGH

event should be processed before others

#define SND_SEQ_PRIORITY_MASK

mask for priority bits

#define SND_SEQ_PRIORITY_NORMAL

normal priority

#define SND_SEQ_TIME_MODE_ABS

absolute timestamp

#define SND_SEQ_TIME_MODE_MASK

mask for time mode bits

#define SND_SEQ_TIME_MODE_REL

relative to current time

#define SND_SEQ_TIME_STAMP_MASK

mask for timestamp bits

#define SND_SEQ_TIME_STAMP_REAL

timestamp in real time

#define SND_SEQ_TIME_STAMP_TICK

Event mode flags

NOTE: only 8 bits available!timestamp in clock ticks
