For HP-UX 11i Version 1.5 (B.11.20), the uname(1) and uname(2) interfaces
are replaced by new confstr(3C) interfaces as a means to obtain
a unique machine identification number. The previous uname(1) and uname(2) interfaces
are supported in HP-UX 11i Version 1.5 (B.11.20), with limitations, and will be obsoleted
in a future release.
The model string returned by the uname(1), uname(2), getconf(1), confstr(3C),
and model(1) interfaces
on HP's Itanium-based platforms will not begin with 9000/,
as has been the case on previous PA based HP-UX systems. Instead,
the model string is, or begins with, ia64.
The following command and function return the string ia64 on
all IPF platforms.
machine field of the utsname structure returned
by uname(2)
The model command, per its existing definition, returns the same
output as uname -m, possibly with additional information. If available,
the additional information can be used to distinguish between different systems.
The command getconf MACHINE_MODEL and the library call confstr(_CS_MACHINE_MODEL,...) will
return the same output as the model command.
Machine ID Compatibility |
 |
Applications running on HP-UX 11i Version 1.5 (B.11.20) that require ID numbers
guaranteed to be unique across all platforms must be converted (a
source code change) to use the new confstr(3C) or getconf(1) interfaces in
place of the uname(2) and uname(1) interfaces.
Applications that do not require completely unique ID numbers may
continue to use the uname(2) and uname(1) interfaces
on this release. However, those applications must change to use
the new interfaces in a future release.
Applications which recognize HP platforms as a class or HP-UX
itself by examining the model string value (e.g., testing for a
leading 9000/) will need to be changed.
