iocblk(9S) Data Structures for Drivers iocblk(9S)NAME
iocblk - STREAMS data structure for the M_IOCTL message type
SYNOPSIS
#include <sys/stream.h>
INTERFACE LEVEL
Architecture independent level 1 (DDI/DKI).
DESCRIPTION
The iocblk data structure is used for passing M_IOCTL messages.
STRUCTURE MEMBERS
int ioc_cmd; /* ioctl command type */
cred_t *ioc_cr; /* full credentials */
uint_t ioc_id; /* ioctl id */
uint_t ioc_flag; /* ioctl flags */
uint_t ioc_count; /* count of bytes in data field */
int ioc_rval; /* return value */
int ioc_error; /* error code */

miocnak(9F) Kernel Functions for Drivers miocnak(9F)NAME
miocnak - Negatively acknowledge an M_IOCTL message
SYNOPSIS
#include <sys/stream.h>
#include <sys/strsun.h>
void miocnak(queue_t *wq, mblk_t *mp, int count, int error);
INTERFACE LEVEL
Solaris DDI specific (Solaris DDI).
PARAMETERS
wq Write queue associated with the read queue to send the M_IOCNAK on.
mp M_IOCTL message.
count Value to set the ioc_count of the iocblk(9S) to.
error Value to set the ioc_error of the iocblk(9S) to.
DESCRIPTION
The miocnak() function converts an M_IOCTL message into an M_IOCNAK message and sends the resulting message upstream.
To convert the message, miocnak() changes the message type to M_IOCNAK, sets the ioc_count and ioc_error members of the iocblk(9S) associ-
ated with mp to the passed-in values, and clears the ioc_rval field. Since payloads cannot currently be associated with M_IOCNAK messages,
count must always be zero. If error is passed as zero, EINVAL is assumed.
RETURN VALUES
None.
CONTEXT
This function can be called from user, kernel or interrupt context.
NOTES
Callers must not hold any locks across a miocnak() that can be acquired as part of put(9E) processing.

Hi All,
Having recently started a new job, a Data Center Migration in fact I have been tasked with looking at some of the older Solaris boxes when I came across this little gem.

For any SunOS 5.XX release, it appears prior to the "login:" prompt (as if a "uname" command is run).
Would anyone know where that initial display of SunOS release comes from upon a remote login and how I can stop if from displaying?
