Comparing 32-bit Interfaces and 64–bit Interfaces

As discussed in Getting Past the 4 Gigabyte Barrier, most 32-bit applications run unchanged in the Solaris 64-bit operating environment. Some applications might only need to be recompiled as 64-bit applications, others need to be converted. This chapter is directed at developers who have determined that their application needs to be recompiled or converted to 64-bit, based on the items discussed in Getting Past the 4 Gigabyte Barrier.
