NAME
       isainfo - describe instruction set architectures

SYNOPSIS
       isainfo [-v] [-b	| -n | -k]

DESCRIPTION
       The  isainfo  utility is	used to	identify various attributes of the in-
       struction set architectures supported on	the currently running  system.
       Among  the  questions it	can answer are whether 64-bit applications are
       supported, or whether the running kernel	uses 32-bit or	64-bit	device
       drivers.

       When  invoked  with  no flags, isainfo prints the name(s) of the	native
       instruction sets	for applications supported by the current  version  of
       the  operating  system.	These will be a	subset of the list returned by
       isalist(1). The subset corresponds to the basic	applications  environ-
       ments supported by the currently	running	system.

OPTIONS
       The following options are supported:

       -b    Prints  the number	of bits	in the address space of	the native in-
	     struction set.

       -k    Prints the	name of	the instruction	set(s) used by	the  operating
	     system  kernel components such as device drivers and STREAMS mod-
	     ules.

       -n    Prints the	name of	the native instruction set  used  by  portable
	     applications  supported  by  the current version of the operating
	     system.

       -v    Prints more detailed information about the	other options.

EXAMPLES
       Example 1: Invoking isainfo on a	32-bit IA platform

       example%	isainfo	-v
       32-bit i386 applications

       example%	isainfo	-k
       i386

       Example 2: Invoking isainfo on a	system running	the  32-bit  operating
       system on a 64-bit SPARC	processor

       example%	isainfo	-n
       sparc
       example%	isainfo	-v
       32-bit sparc applications
       example%	isainfo	-kv
       32-bit sparc kernel modules

       Example	3:  Invoking isainfo on	the same hardware platform (that is, a
       64-bit SPARC processor) running the 64-bit operating system

       example%	isainfo
       sparcv9 sparc
       example%	isainfo	-n
       sparcv9
       example%	isainfo	-v
       64-bit sparcv9 applications 32-bit sparc	applications
       example%	isainfo	-vk
       64-bit sparcv9 kernel modules

EXIT STATUS
       Non-zero
	     Flags are not specified correctly,	or the command	is  unable  to
	     recognize attributes of the system	on which it is running.	An er-
	     ror message is printed to stderr.

ATTRIBUTES
       See attributes(5) for descriptions of the following attributes:
