FLUSHBAND(9F) Kernel Functions for Drivers FLUSHBAND(9F)
flushband - flush messages for a specified priority band
#include <sys/stream.h>
void flushband(queue_t *q, unsigned char pri, int flag);
Architecture independent level 1 (DDI/DKI).
q
Pointer to the queue.
pri
Priority of messages to be flushed.
flag
Valid flag values are:
FLUSHDATA
Flush only data messages (types M_DATA, M_DELAY,
M_PROTO, and M_PCPROTO ).
FLUSHALL
Flush all messages.
The flushband() function flushes messages associated with the
priority band specified by pri. If pri is 0, only normal and high
priority messages are flushed. Otherwise, messages are flushed from
the band pri according to the value of flag.
The flushband() function can be called from user, interrupt, or
kernel context.
