These usually are set to the address of the module-specific data structure for the minor device. .sp .in +2 .nf 1 xxxclose(q, flag) 2 queue_t *q; 3 int flag; 4 { 5 q->q_ptr = NULL; 6 WR(q)->q_ptr = NULL; . . . 7 } .fi .in -2 .sp .SH SEE ALSO .sp .LP \fBclose\fR(9E), \fBOTHERQ\fR(9F), \fBRD\fR(9F) .sp .LP \fIWriting Device Drivers in Oracle Solaris 11.4\fR .sp .LP \fISTREAMS Programming Guide\fR
