#include <sys/ddi.h> #include <sys/sunddi.h> void ddi_mem_put8(ddi_acc_handle_t handle, uint8_t *dev_addr, uint8_t value); void ddi_mem_put16(ddi_acc_handle_t handle, uint16_t *dev_addr, uint16_t value); void ddi_mem_put32(ddi_acc_handle_t handle, uint32_t *dev_addr, uint32_t value); void ddi_mem_put64(ddi_acc_handle_t handle, uint64_t *dev_addr, uint64_t value); PARAMETERS
handle The data access handle returned from setup calls, such as ddi_regs_map_setup(9F). dev_addr Base device address. value The data to be written to the device. INTERFACE LEVEL
Solaris DDI specific (Solaris DDI). DESCRIPTION
These routines generate a write of various sizes to memory space or allocated DMA memory. The ddi_mem_put8(), ddi_mem_put16(), ddi_mem_put32(), and ddi_mem_put64() functions write 8 bits, 16 bits, 32 bits and 64 bits of data, respectively, to the device address, dev_addr, in memory space. 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. SEE ALSO

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.
