NAME

outb, outw, outl, repoutsb, repoutsw, repoutsd - write to an I/O port

SYNOPSIS

#include <sys/ddi.h>
#include <sys/sunddi.h> 

void outb(int port, unsigned char value);

void outw(int port, unsigned short value);

void outl(int port, unsigned long value);

void repoutsb(int port, unsigned char *addr, int count);

void repoutsw(int port, unsigned short *addr, int count);

void repoutsd(int port, unsigned long *addr, int count);

INTERFACE LEVEL

The functions described here are obsolete. For the outb(), outw(), and outl() functions use, respectively, ddi_put8(9F), ddi_put8(9F), and ddi_put8(9F) instead. For repoutsb(), repoutsw(), andrepoutsl(), use, respectively, ddi_rep_put8(9F), ddi_rep_put8(9F), and ddi_rep_put8(9F) instead.

PARAMETERS

port

: A valid I/O port address.

value

: The data to be written to the I/O port.

addr

: The address of a buffer from which the values will be fetched.

count

: The number of values to be written to the I/O port.

DESCRIPTION

These routines write data of various sizes to the I/O port with the address specified by port.

The outb(), outw(), and outl() functions write 8 bits, 16 bits, and 32 bits of data respectively, writing the data specified by value.

The repoutsb(), repoutsw(), and repoutsd() functions write multiple 8-bit, 16-bit, and 32-bit values, respectively. count specifies the number of values to be written. addr is a pointer to a buffer from which the output values are fetched.
