NAME
       ddi_io_put8, ddi_io_put16, ddi_io_put32, ddi_io_putb, ddi_io_putl, ddi_io_putw - write data to the mapped device register in I/O space

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

       void ddi_io_put8(ddi_acc_handle_t handle, uint8_t *dev_addr,
	    uint8_t value);

       void ddi_io_put16(ddi_acc_handle_t handle, uint16_t *dev_addr,
	    uint16_t value);

       void ddi_io_put32(ddi_acc_handle_t handle, uint32_t *dev_addr,
	    uint32_t value);

INTERFACE LEVEL
       Solaris	DDI  specific  (Solaris  DDI).	The ddi_io_put8(), ddi_io_put16(), ddi_io_put32(), ddi_io_putb(), ddi_io_putl(), and ddi_io_putw()
       functions are obsolete. The  ddi_put8(9F)  function  replaces  ddi_io_put8().  The  ddi_put16(9F)  function  replaces  ddi_io_put16().  The
       ddi_put32(9F)  function	replaces  ddi_io_put32().  The	ddi_put8(9F)  function replaces ddi_io_putb(). The ddi_put32(9F) function replaces
       ddi_io_putl(). The ddi_put16(9F) function replaces ddi_io_putw().

PARAMETERS
       handle	   Data access handle returned from setup calls, such as ddi_regs_map_setup(9F).

       dev_addr    Base device address.

       value	   Data to be written to the device.

DESCRIPTION
       These routines generate a write of various sizes to the device address, dev_addr, in I/O  space.  The  ddi_io_put8(),  ddi_io_put16(),  and
       ddi_io_put32() functions write 8 bits, 16 bits, and 32 bits of data, respectively, to the device address, dev_addr.

       Each  individual  datum will automatically be translated to maintain a consistent view between the host and the device based on the encoded
       information in the data access handle.  The translation may involve byte-swapping if the host and the device have incompatible endian char-
       acteristics.

CONTEXT
       These functions can be called from user, kernel, or interrupt context.
