#include <sys/ddi.h> #include <sys/sunddi.h> uint8_t ddi_get8(ddi_acc_handle_t handle, uint8_t *dev_addr);
uint16_t ddi_get16(ddi_acc_handle_t handle, uint16_t *dev_addr);

uint64_t ddi_get64(ddi_acc_handle_t handle, uint64_t *dev_addr);
The data access handle returned from setup calls, such as ddi_regs_map_setup(9F).
Base device address.
The ddi_get8(), ddi_get16(), ddi_get32(), and ddi_get64() functions read 8 bits, 16 bits, 32 bits and 64 bits of data, respectively, from 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 characteristics.
For certain bus types, you can call these DDI functions from a high-interrupt context. These types include ISA and SBus buses. See sysbus(4), isa(4), and sbus(4) for details. For the PCI bus, you can, under certain conditions, call these DDI functions from a high-interrupt context. See pci(4).
These functions return the value read from the mapped address.
These functions can be called from user, kernel, or interrupt context.

The functions described in this manual page previously used symbolic names which specified their data access size; the function names have been changed so they now specify a fixed-width data size. See the following table for the new name equivalents:
