NAME
      isainfo - describe instruction set architectures
 


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


DESCRIPTION
      The isainfo utility is used to identify  various  attributes
      of  the  instruction  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 environments 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 instruction set.
 
      -k    Prints the name of the instruction set(s) used by  the
            operating  system  kernel  components  such  as device
            drivers and STREAMS modules.
 
      -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

 User Commands                                          isainfo(1)
 
 
 
      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 error message is printed to stderr.
