ldi_read(9F) Kernel Functions for Drivers ldi_read(9F)NAME
ldi_read, ldi_write - Read and write from a device
SYNOPSIS
#include <sys/sunldi.h>
int ldi_read(ldi_handle_t lh, struct uio *uiop, cred_t *cr);
int ldi_write(ldi_handle_t lh, struct uio *uiop, cred_t *cr);
PARAMETERS
lh Layered handle.
cr Pointer to a credential structure used to open a device.
uiop Pointer to the uio(9S) structure. uio(9S) specifies the location of the read or write data. (Either userland or kernel.)
DESCRIPTION
The ldi_read() function passes a read request to the device entry point for the device specified by the layered handle. This operation is
supported for block, character, and streams devices.
The ldi_write() function passes a write request to the device entry point for a device specified by the layered handle. This operation is
supported for block, character, and streams devices.
RETURN VALUES
The ldi_read() and ldi_write() functions return 0 upon success. If a failure occurs before the request is passed to the device, the pos-
sible return values are shown below. Otherwise any other error number may be returned by the device.
EINVAL Invalid input parameters.
ENOTSUP Operation is not supported for this device.
CONTEXT
These functions may be called from user or kernel context.

ldi_aread, ldi_awrite - Issue an asynchronous read or write request to a device
SYNOPSIS
#include <sys/sunldi.h>
int ldi_aread(ldi_handle_t lh, struct aio_req *aio_reqp, cred_t *cr);
int ldi_awrite(ldi_handle_t lh, struct aio_req *aio_reqp, cred_t *cr);
PARAMETERS
lh Layered handle.
cr Pointer to a credential structure.
aio_reqp Pointer to the aio_req(9S) structure that describes where the data is to be stored or obtained from.
DESCRIPTION
The ldi_awrite() function passes an asynchronous write request to a device entry point specified by the layered handle. This operation is
supported for block and character devices.
The ldi_aread() function passes an asynchronous read request to a device entry point specified by the layered handle. This operation is
supported for block and character devices.
RETURN VALUES
The ldi_awrite() and ldi_aread() functions return 0 upon success. If a failure occurs before the request is passed on to the device, the
possible return values are shown below. Otherwise any other error number may be returned by the device.
EINVAL Invalid input parameters.
ENOTSUP Operation is not supported for this device.
CONTEXT
These functions may be called from user 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?
