.SH DESCRIPTION
.sp
.LP
The \fBprint()\fR routine is called by the kernel when it has detected an
exceptional condition (such as out of space) in the device.  To display the
message on the console, the driver should use the  \fBcmn_err\fR(9F) kernel
function. The driver should print the message along with any driver specific
information.
.SH RETURN VALUES
.sp
.LP
The  \fBprint()\fR routine should return \fB0\fR for success, or the
appropriate error number.  The  \fBprint\fR routine can fail if the driver
implemented a non-standard  \fBprint()\fR routine that attempted to perform
error logging, but was unable to complete the logging for whatever reason.
