Solaris DDI Specific (Solaris DDI)
The offset in bytes from the base of the mapped resource.
The data to be written to the device.
These functions generate a write of various sizes to the mapped memory or device register.
The csx_Put8(), csx_Put16(), csx_Put32(), and csx_Put64() functions write 8 bits, 16 bits, 32 bits, and 64 bits of data, respectively, to the device address represented by the handle, handle, at an offset in bytes represented by the offset, offset.
Data that consists of more than one byte 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.
These functions may be called from user, kernel, or interrupt context.
