IOC_CONVERT_FROM(9F) Kernel Functions for Drivers IOC_CONVERT_FROM(9F)NAME
IOC_CONVERT_FROM - determine if there is a need to translate M_IOCTL contents.
SYNOPSIS
#include <sys/stream.h>
uint_t IOC_CONVERT_FROM(struct iocblk *iocp);
INTERFACE LEVEL
Solaris DDI Specific (Solaris DDI)
PARAMETERS
iocp A pointer to the M_IOCTL control structure.
DESCRIPTION
The IOC_CONVERT_FROM macro is used to see if the contents of the current M_IOCTL message had its origin in a different C Language Type
Model.
RETURN VALUES
IOC_CONVERT_FROM() returns the following values:
IOC_ILP32 This is an LP64 kernel and the M_IOCTL originated in an ILP32 user process.
IOC_NONE The M_IOCTL message uses the same C Language Type Model as this calling module or driver.
CONTEXT
IOC_CONVERT_FROM() can be called from user or interrupt context.

mcopyin(9F) Kernel Functions for Drivers mcopyin(9F)NAME
mcopyin - Convert an M_IOCTL or M_IOCDATA message to an M_COPYIN
SYNOPSIS
#include <sys/stream.h>
#include <sys/strsun.h>
void mcopyin(mblk_t *mp, void *private, size_t size, void * useraddr);
INTERFACE LEVEL
Solaris DDI specific (Solaris DDI).
PARAMETERS
mp M_IOCTL or M_IOCDATA message.
private Value to which the cq_private field of copyreq(9S) is set.
size Value to which the cq_size field of copyreq(9S) is set.
useraddr Optionally, the value to which the cq_addr field of copyreq(9S) is set.
DESCRIPTION
The mcopyin() function converts an M_IOCTL or M_IOCDATA message into an M_COPYIN message using the supplied arguments.
To convert the message, mcopyin() changes the message type to M_COPYIN, and its payload from a iocblk(9S) to a copyreq(9S). Since the
iocblk(9S) and copyreq(9S) are designed to overlay one another, the only fields which must be updated are cq_private, cq_size, and cq_addr,
which are set to the supplied values. If useraddr is passed as NULL, mp must be a transparent M_IOCTL, and cq_addr is assigned the pointer-
sized quantity found at mp->b_cont->b_rptr.
Any trailing message blocks associated with mp are freed.
RETURN VALUES
None.
CONTEXT
This function can be called from user, kernel or interrupt context.

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?
