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_put16(9F), and
       ddi_put32(9F)  instead.	For  repoutsb(),  repoutsw(),  andrepoutsl(),  use,   respectively,   ddi_rep_put8(9F),   ddi_rep_put16(9F),   and
       ddi_rep_put32(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.

CONTEXT
       These functions may be called from user or interrupt context.
