General Issues

Before starting to clean up a device driver for the 64-bit environment, you should understand how the 32-bit environment differs from the 64-bit environment. In particular, it is important to be familiar with the C language data type models ILP32 and LP64, and to be aware of driver-specific issues. Driver-specific issues are the subject of this appendix, while more general issues are covered extensively in Solaris 64-bit Developer's Guide.
