SYNOPSIS
     #include <sys/utsname.h>

     int
     uname(struct utsname *u)

DESCRIPTION
     The uname() function provides system information strings.  The utsname
     structure contains a set of these strings:

           struct utsname {
                   char    nodename[];
                   char    sysname[];
                   char    release[];
                   char    version[];
                   char    machine[];
           };

     These fields contain the following information:

     nodename  The current hostname, similar to output from hostname(1).

     sysname   The name of the operating system.

     release   The current release (typically numbers separated by dots).

     version   The current version (typically a number).

     machine   The architecture identifier, similar to output from machine(1).

     The uname() function returns a nonnegative value if it succeeds in get-
     ting system identifiers, otherwise it returns -1 and sets errno appropri-
     ately.
