mcopymsg(9F) Kernel Functions for Drivers mcopymsg(9F)NAME
mcopymsg - Copy message contents into a buffer
SYNOPSIS
#include <sys/stream.h>
#include <sys/strsun.h>
void mcopymsg(mblk_t *mp, void *buf);
INTERFACE LEVEL
Solaris DDI specific (Solaris DDI).
PARAMETERS
mp Message to be copied.
buf Buffer in which to copy.
DESCRIPTION
The mcopymsg() function copies the contents of the specified message into the specified buffer. If the message consists of more than a sin-
gle message block, the contents of each message block are placed consecutively into the buffer.
The provided buffer must be large enough to accommodate the message. If the buffer is not large enough, the results are unspecified. The
msgsize(9F) function can be used to calculate the total size of the message beforehand.
RETURN VALUES
None.
CONTEXT
This function can be called from user, kernel or interrupt context.

merror - Send an M_ERROR message upstream
SYNOPSIS
#include <sys/stream.h>
#include <sys/strsun.h>
void merror(queue_t *wq, mblk_t *mp, int error);
INTERFACE LEVEL
Solaris DDI specific (Solaris DDI).
PARAMETERS
wq Write queue associated with the read queue to send the M_ERROR on.
mp Optionally, a STREAMS message to convert to an M_ERROR.
error Error code to include in the M_ERROR message.
DESCRIPTION
The merror() function constructs an M_ERROR message, and sends the resulting message upstream.
If mp is NULL, merror() allocates a one-byte M_ERROR message. If mp is non-NULL, merror() attempts to convert the passed-in message to an
M_ERROR. However, if the passed-in message has more than one reference (see dupmsg(9F)), or if it is of zero length, it is freed and a new
message is allocated.
If the allocation or conversion fails, merror() silently fails. Otherwise, the resulting one-byte data block is assigned the specified
error code and sent upstream.
RETURN VALUES
None.
CONTEXT
This function can be called from user, kernel or interrupt context.
NOTES
Callers must not hold any locks across an merror() that can be acquired as part of put(9E) processing.

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?
