NAME

inb, inw, inl, repinsb, repinsw, repinsd - read from an I/O port

SYNOPSIS

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

unsigned char inb(int port);

unsigned short inw(int
port);

unsigned long inl(int port);

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

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

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

INTERFACE LEVEL

The functions described here are obsolete. For the inb(), inw(), and inl() functions, use, respectively, ddi_get8(9F), ddi_get8(9F), and ddi_get8(9F) instead. For repinsb(), repinsw(), andrepinsl(), use, respectively, ddi_rep_get8(9F), ddi_rep_get8(9F), and ddi_rep_get8(9F) instead.

PARAMETERS

port

: A valid I/O port address.

addr

: The address of a buffer where the values will be stored.

count

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

DESCRIPTION

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

The inb(), inw(), and inl() functions read 8 bits, 16 bits, and 32 bits of data respectively, returning the resulting values.

The repinsb(), repinsw(), and repinsd() functions read multiple 8-bit, 16-bit, and 32-bit values, respectively. count specifies the number of values to be read. A pointer to a buffer will receive the input data; the buffer must be long enough to hold count values of the requested size.
