Solaris 64-bit Developer's Guide

Extensions to sysinfo(2)

New sysinfo(2) subcodes in the Solaris S10 operating environment enable applications to ascertain more information about the available instruction set architectures.

For example, the name of the 64-bit ABI available on the system (if any), is available using the SI_ARCHITECTURE_64 subcode. See sysinfo(2) for details.
