ureadc(9F) Kernel Functions for Drivers ureadc(9F)NAME
ureadc - add character to a uio structure
SYNOPSIS
#include <sys/uio.h>
#include <sys/types.h>
int ureadc(int c, uio_t *uio_p);
INTERFACE LEVEL
Architecture independent level 1 (DDI/DKI).
PARAMETERS
c The character added to the uio(9S) structure.
uio_p Pointer to the uio(9S) structure.
DESCRIPTION
ureadc() transfers the character c into the address space of the uio(9S) structure pointed to by uio_p, and updates the uio structure as
for uiomove(9F).
RETURN VALUES
0 is returned on success and EFAULT on failure.
CONTEXT
ureadc() can be called from user or interrupt context.

uiomove - copy kernel data using uio structure
SYNOPSIS
#include <sys/types.h>
#include <sys/uio.h>
int uiomove(caddr_t address, size_t nbytes, enum uio_rw rwflag,
uio_t *uio_p);
INTERFACE LEVEL
Architecture independent level 1 (DDI/DKI).
PARAMETERS
address Source/destination kernel address of the copy.
nbytes Number of bytes to copy.
rwflag Flag indicating read or write operation. Possible values are UIO_READ and UIO_WRITE.
uio_p Pointer to the uio structure for the copy.
DESCRIPTION
The uiomove() function copies nbytes of data to or from the space defined by the uio structure (described in uio(9S)) and the driver.
The uio_segflg member of the uio(9S) structure determines the type of space to or from which the transfer is being made. If it is set to
UIO_SYSSPACE, the data transfer is between addresses in the kernel. If it is set to UIO_USERSPACE, the transfer is between a user program
and kernel space.
rwflag indicates the direction of the transfer. If UIO_READ is set, the data will be transferred from address to the buffer(s) described by
uio_p. If UIO_WRITE is set, the data will be transferred from the buffer(s) described by uio_p to address.
In addition to moving the data, uiomove() adds the number of bytes moved to the iov_base member of the iovec(9S) structure, decreases the
iov_len member, increases the uio_offset member of the uio(9S) structure, and decreases the uio_resid member.
This function automatically handles page faults. nbytes does not have to be word-aligned.
RETURN VALUES
The uiomove() function returns 0 upon success or EFAULT on failure.
CONTEXT
User context only, if uio_segflg is set to UIO_USERSPACE. User, interrupt, or kernel context, if uio_segflg is set to UIO_SYSSPACE.
SEE ALSO ureadc(9F), uwritec(9F), iovec(9S), uio(9S)
Writing Device Drivers
WARNINGS
If uio_segflg is set to UIO_SYSSPACE and address is selected from user space, the system may panic.

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?
