UNAME(2V)                                                            UNAME(2V)



NAME
       uname - get information about current system

SYNOPSIS
       #include <&lt;sys/utsname.h>&gt;

       int uname (name)
       struct utsname *name;

DESCRIPTION
       uname()  stores information identifying the current operating system in
       the structure pointed to by name.

       uname() uses the structure defined in <&lt;sys/utsname.h>&gt;, the  members  of
       which are:

              struct utsname {
                     char sysname[9];
                     char nodename[9];
                     char nodeext[65-9];
                     char release[9];
                     char version[9];
                     char machine[9];
              }

       uname()  places  a  null-terminated character string naming the current
       operating system in the character array sysname; this string is "SunOS"
       on  Sun  systems.  nodename is set to the name that the system is known
       by on a communications network; this is the same value as  is  returned
       by  gethostname(2).  release and version are set to values that further
       identify the operating system.  machine is set to a standard name  that
       identifies  the hardware on which the SunOS system is running.  This is
       the same as the value displayed by arch(1).

RETURN VALUES
       uname() returns:

       0      on success.

       -1     on failure.

NOTES
       nodeext is provided for backwards  compatability  with  previous  SunOS
       Releases  and  provides  space  for node names longer than eight bytes.
       Applications should not use nodeext.  To be maximally portable,  appli-
       cations  that  want  to copy the node name to another string should use
       strlen(nodename) rather than the constant 9 or sizeof(nodename) as  the
       size of the target string.

       System  administrators  should note that systems with node names longer
       than eight bytes do not conform  to  IEEE  Std  1003.1-1988,  System  V
       Interface  Definition  (Issue 2), or X/Open Portability Guide (Issue 2)
       requirements.
