NAME

       uname - get system identification

SYNOPSIS

       #include <sys/utsname.h>

       int uname (struct utsname *name);

DESCRIPTION

       The  uname()  function  stores  null-terminated  strings of information
       identifying the current system into the structure referenced by name.

       The utsname structure is defined in the  <sys/utsname.h>  header  file,
       and contains the following members:

              sysname
                     Name of the operating system implementation.

              nodename
                     Network name of this machine.

              release
                     Release level of the operating system.

              version
                     Version level of the operating system.

              machine
                     Machine hardware platform.

RETURN VALUES

       If  uname() is successful, 0 is returned, otherwise, -1 is returned and
       errno is set appropriately.

CAVEATS

       The inclusion of the nodename member in the utsname structure does  not
       imply  that  it is sufficient information for interfacing to communica‐
       tions networks.

STANDARDS

       The uname() function conforms to IEEE Std1003.1-1988 (``POSIX'').

HISTORY

       The uname() function first appeared in 4.4BSD.
