uname(S)                       6 January 1993                       uname(S)


 Name

    uname - get name of current system

 Syntax


    cc  . . .  -lc


    #include <sys/utsname.h>

    int uname (name)
    struct utsname *name;


 Description

    The uname system call stores information identifying the current system
    in the structure pointed to by name.

    The uname system call uses the utsname structure defined in
    <sys/utsname.h> whose members are:

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

    The uname system call returns a null-terminated character string naming
    the current system in the character array sysname.  nodename contains the
    name that the system is known by on a communications network; however the
    inclusion of this member does not imply that it is sufficient information
    for interfacing to communications networks.  release and version further
    identify the operating system.  machine contains a standard name that
    identifies the hardware that the system is running on.
