Solaris (64-bit) Developer's Guide is the official Solaris 64-bit operating system developer's guide, which mainly introduces 64-bit computing, when to use 64-bit, comparing 32-bit interfaces and 64-bit interfaces, and converting applications.
The guide provides an overview of Solaris 64‑bit support, describing the removal of the 4 GB limit and the new virtual address space. It compares the 32‑bit LP32 data model with the 64‑bit LP64 model and outlines compatibility considerations.
It also details migration steps, including required tools such as isaexec, kernel memory access methods, and the use of appropriate libraries. Appendices list common issues and provide reference material for developers transitioning applications to 64‑bit Solaris. This manual is written in Chinese.
| Virtual Address Limit | No 4 GB limit |

Use migration tools such as isaexec, adjust data models to LP64, rebuild with 64‑bit libraries, and modify code that assumes 32‑bit pointer sizes.
