between fork() and vfork() calls. See vfork(2) and fork(2) for details.

8. When an emulated application makes any system call that returns the processor-related information,

then under emulation, Aries returns information pertinent to a PA-RISC 2.0 processor, even though

the emulated application runs on an Itanium-based machine. For instance, a call made to

sys-

conf

(2), with _SC_CPU_VERSION

, will return CPU_PA_RISC2_0

. This is an Aries policy, that an

emulated application sees a complete PA-RISC environment on Itanium-based system. If the applica-

tion requires that it be able to determine that it is running on an Itanium-based machine, one method

is for the application to use the

system() call and the Itanium-based native command

getconf to

get the required ﬁelds. See system (3S), getconf(1), and sysconf(2) for more information.
